______________________________________ BEFORE: DAUGHTREY and SUTTON, Circuit Judges, and FORESTER, * District Judge. MARTHA CRAIG DAUGHTREY, Circuit Judge. The plaintiff, William Parries, appeals from the district court’ s order granting summary judgm ent to his former employer, Makino, Inc., in an action Parries filed chargi ng violation of Title V II of the 1964 Civil Rights Act, 42 U.S.C. §§ 2000e et seq., and intentional infliction of emotional distress under Ohio state law. Parries was initially terminated in November 1999 but was reinstated by order of an arbitrator in August 2000. In June 2001, he was terminated a second time. In his complaint, Parries alleged that both actions we re based on race discrimination and that the- 2 - employer had illegally retaliated against him fo r filing a discriminati on charge with the Ohio Civil Rights Commission after his termination in 1999. The district court granted summary judgment to Makino on all counts, finding that the plaintiff had not made out a prima facie case of either discrimination or retaliation. On appeal, we c onclude that the district court correctly determined that the discr imination claim failed for lack of a prima facie case. But, contrary to the district court’s determination, we also conclude that the plaintiff did succeed in establishing a prima facie case of retaliati on. What the plaintiff failed to do, however, was to rebut the defendant’s legitimate busine ss reason for his termination and, as a result, we hold that summary judgment was appropriately entered in the defendant’s favor.

FACTUAL AND PROCEDURAL BACKGROUND Parries began working for Makino, Inc., in 1990 and was employed there continuously until his first termination in Nove mber 1999. He was one of very few AfricanAmerican employees among the uni on workforce at Makino. Parries believed that he had experienced disparate treatment based on his mi nority status almost from the beginning of his employment at Makino and, as a result, he filed his first complaint with the Ohio Civil Rights Commission in March 1990 and lodged severa l more in the following years. This case, however, deals solely with events leadi ng to his terminations in 1999 and 2001, and the only protected activity alleged as a basis for his retaliation claim is the charge he filed with the Ohio Commission following his 1999 termination.

The facts in the record est ablish that in early 1998, Ma kino promoted Parries to the position of electrical technician, which pl aced him under the direct supervision of Don- 3 - Hoerlein and Jeff Reichert. In September 1998, a different supervisor observed Parries returning late from lunch break. That supervisor, Sisson, gave Parri es a verbal warning and placed a note in Parries’s file. Makino us ed a system of “progre ssive discipline” under which an employee goes though three steps of di scipline levels before being subject to discharge. However, the note that Sisson wrote did not countas a formal discipline step, and Parries was not aware of it s existence. In November 1998, Reichert did place Parries on the first level of discipline a fter observing him returning late from lunch. Parries said that he had been talking with two other employees about a company meeting he attended earlier in the day. In March 1999, Parries wa s placed on the second step of discipline when he returned late from break time. Parries’s explanation was that he was a candidate for a union leadership position and had been discussing contract issues with a fellow union member. A few days later, Parries missed work wit hout informing his supervisor in advance. Under Makino’s point-based attendance policy, an employee earned cred it points for good attendance and penalty points for any absences. Credits could be applied against absences, but only if the employee called in within the first two hours of an absence. Parries’s absence placed him over the ten-pointlimit and thus subjected him to discipline. Because Parries had forgotten to call in the morning of his absence, Hoerlein refused Parries’s post hoc request to apply his credit poi nts. Hoerlein placed Parries on the third disciplinary level for this infraction. In October 1999, Parries was recor ded as having committed three disciplinary infractions that were not individually punis hed but that led up to a “last chance agreement.”- 4 - Specifically, on October 12, a Makino supervisor observed Parries clocking into work and then returning to his car, parki ng, and re-entering the facility. The supervisor reported the incident to Reichert, who gave Parries a verbal warning. Two days later, on October 14, Parries returned five minuteslate from break after spending the time discussing safety issues with other union members. The next day, on October 15, Parries remained away from his workstation for longer than permi tted for a discussion with the union president, who was a fellow employee. In response to these three incidents, Makino management met with Parries and issued the “last chance agr eement.” The agreementwas in lieu, they said, of the usual fourth step of discip line, which was permanent termination. The agreement provided that “[a]ny violation of this ‘Last Chance Agreement’ will result in disciplinary action, up to and including terminati on.” Parries declined to sign the document. Invoking the terms of the “last chanc e agreement,” Makino terminated Parries a month later, in November 1999. Earlier that month, Parrieshad lost his employee badge and could not clock in and out of work in the usual fashion. Parries called his supervisor on the phone to check in verbally for the first tw o days, but there is a dispute as to whether he did so for the following three days. Al though Parries maintained that he saw Reichert on the floor and asked him to check him in, Reichert had no record of this. Reichert concluded that Parries had violated the “last chance agreement” and contacted the manager of labor relations at Makino, who decided to discharge Parri es. In response, Parries filed a claim of race discriminat ion and retaliation with the Ohio Civil Rights Commission, which found that “pr obable cause d[id] exist” to credit Parries’s allegations of discrimination.- 5 - Parries also challenged his termination in arbitration, and he won. The arbitrator concluded that Parries had not violat ed the “last chance agreement” and ordered reinstatement with back pay, which occurred on August 8, 2000. His new position was as a unit assembler under the supervision of Hoerlein. On ce again, Parries immediately began to have run-ins with his supervisors. Twice in August, Hoerlein spoke to Parries about making “loud noises” while at his work st ation. In November 2000, Hoerlein gave Parries a five-day suspension after findi ng him away from his work-station without permission. Makino later rescinded the su spension and instead gave Parries a “final warning.” In response to this incident, Parri es filed a retaliation claim with the Ohio Civil Rights Commission. In December 2000, Parries again faced discipline, this time for attempting to tape-record a meeting between the union and Makino management. Although Parries claimed that the anti-reco rding policy was never made explicit, the company insisted that he had been told in a prev ious meeting that he was not allowed to make such tape-recordings. In January 2001, Parries received a “final warning” from Ed Morris, the supervisor under whom he was t hen working, for improperly recording his hours. Parries then filed ye t another complaint with the Oh io Civil Rights Commission. In March, Morris gave Parries two verbal and one written warning for his poor work performance.

The situation came to a head in June 2001 when Parries entered into an argument with Morris and Hoerlein about whether Hoerle in had given employees certain information about their overtime hours. In the course ofthe argument, Parries called Hoerlein a liar- 6 - and told him to “get some balls.” Makino t hen terminated Parries’s employment, citing his poor performance, repeated discipli nary problems, and insubordination.

DISCUSSION

A. The Discrimination Claims “[A] plaintiff may establish a prima facie ca se of discrimination either by presenting direct evidence of intentional discrimination by the defendant or by showing the existence of facts which create an infe rence of discrimination.” Talley v. Bravo Pitino Rest. , 61 F.3d 1241, 1248 (6th Cir. 1995) (citati ons omitted). Although Parries attempted, unsuccessfully, to produce direct evidence of discrimination in regard to the defendant’s actions, the bulk of the evidence in this case was aimed at “c reat[ing] an inference ofdiscrimination.” To show an inference of discrimination, McDonnell Douglas Corp. v. Green , 411 U.S. 792 (1973), and Texas Department of Community Affairs v. Burdine , 450 U.S. 248 (1981), mandate a showing that the plaintiff (1) was a member of a protected class; (2) was discharged; (3) was qualified for the positi on; and (4) was replaced by a person outside the class. There is no dis pute in this case that Parri es established the first three McDonnell Douglas factors for both his 1999 and 2001 terminations. The district court found, however, that Parries had not establis hed that he had been replaced by a non-minority worker in both instances and had therefore failed to make outa circumstantial case of discrimination. Following Parries’s dismissal in 1999, Makino filled his position with outside contractors. The record contains no info rmation about their ethnicity or race because- 7 - Parries failed to produce any such evidenc e. Hence, Parries has not shown he was replaced with a non-minority person, the fourth McDonnell Douglas element. Makino maintains that Parries was not replaced at all, but rather t hat his position was eliminated. Nevertheless, instead of showing the fourth McDonnell Douglas element, a plaintiff may make out a prima facie case by showi ng “that a comparable non- protected person was treated better.” Mitchell v. Toledo Hosp. , 964 F.2d 577, 582-83 (6th Cir. 1992). To establish disparate treatment, the plaintiff mustshow that he was similarly-situated in all relevant aspects to the comparable worker. See Pierce v. Commonwealth Life Ins. Co. , 40 F.3d 796, 802 (6th Cir. 1994). In a discriminat ory discipline or firing context, “similarlysituated” means that “the indi viduals with whom the plaintiff seeks to compare his/her treatment must have dealt with the same supervisor, have been subject to the same standards and have engaged in the same conduct wit hout such differentiating or mitigating circumstances that would disti nguish their conduct or the employ er’s treatment of them for it.” Mitchell , 964 F.2d at 583. Although the com parison need not involve identical misconduct, the misconduct must be of comparable seriousness. See Hollins v. Atl. Co., Inc. , 188 F.3d 652, 659 (6th Cir. 1999). Parries passed through four stages of disciplinary action prior to his 1999 termination. He now contends that a showi ng of disparate treatment in even one of the stages invalidates his final termination because the termination was built upon the successive disciplinary measures. However, in reviewing the individual disciplinary actions and the evidence of comparables produced, we cannot say thatany one of the employer’s actions meets the Mitchell similarly-situated standard. View ed as a whole, the record of- 8 - discipline suggests that Parries, as one of t he very few African-American employees, may have been subjected to more intense scrutiny by his employers than were other, nonminority workers, but the same evidence does not establish legally disparate treatment. For example, the record shows that Parrieswas placed on the first level of discipline on November 17, 1998, for returning half-an-hourlate from his l unch break. Parries contended that he was 15 minutes late because he started his lunch break late due to a company meeting that ran long. Then, on his way back from lunch, two other employees questioned him about the contents ofthe meeting. When Parries returned to his work station, supervisor Reichert confronted him about being late. Parries complained that he was written up but the two white employees with whom he had been conversing received no discipline. However, Parries did not show that he was similarly-si tuated to his two coworkers; he presented no evidence that Reichert was a supervisor of the two white men, that they were not on an approved break, that Reichert saw the other men away from their work stations, or even that they actually wereaway from their work stations while talking to Parries. The second disciplinary action occurred on March 15, 1999, when Parries was written up for returning late from lunch after discussing union issues with co-workers as part of his campaign for a union leadership position. Parries claimed that it was common practice for union candidates to ta ke a few minutes of work time to explain issues to their co-workers. Parries submitted declarations from two co-workers alleging that they had each engaged in campaigning on company time and had not been punished for it. Again, however, Parries did not show that he was si milarly-situated to those two co-workers- 9 - because there was no indication of who the workers’ supervisors were, whether the supervisors were aware of the practice, w hen the co-workers’ camp aigning occurred, or whether it was done in a simila r manner. To make out a caseof disparate treatment, the plaintiff must produce specific facts showing he and the non -minority employee engaged in similar conduct. See Hardy v. Eastman Chem. Co. , Docket No. 01-5361, 2002 WL 31553926 (6th Cir. Nov. 12, 2002). That require ment was not met in this instance. Parries was placed on the third disciplinary level on March 22, 1999, after an unscheduled absence caused him to exceed his allowable “absentee points” and he failed to call in as required by company rules. As noted above, supervisor Hoerlein refused to allow Parries to apply his good points retroactively and suspended Parries for three days. In contrast, the plaintiff noted, a white co -worker, Brett Manning, similarly exceeded his permissible absentee points in 1998 without calling in, yet Hoerlein allowed him to apply his good points retroactively. According to Ma kino, the difference in treatment was due to the fact that at the time he was permi tted to apply the offset, Manning had been an employee of Makino for only a few months and told supervisor Hoerlein that he had misunderstood the absentee policy. Apparently Hoerlein had then explained the policy to him and warned him not to engage in another infr action. By contrast, Parries had been a Makino employee for almost ten years and was fully familiar with the policy. Although the call is a close one, we cannot say that the di strict court erred in finding that Manning’s status as a recent employee unfamiliar with the protocol co nstituted “differentiating or mitigating circumstances that would distinguish [his] conduct or the employer’s treatment of [him] for it.” Mitchell , 964 F.2d at 583. Indeed, in 1999 Manning exceeded his allowable- 10 - absentee points and was subjected tothe usual discipline, a thr ee-day suspension. Finally, we are not persuaded by the test imony of another white co-worke r, Kincaid, who testified that some employees were allowed to apply good points to absences retrospectively, because Kincaid was unable to give any details as to when or to whom this happened or what supervisor was involved. On October 18, 1999, Makino gave Parries a “last chance” warning as a result of three additional minor infractions. For each one of these infractions, Parries offered substantial evidence that a si milarly-situated white employee was treated better. However, Parries was disciplined for the combination of the three, not each individual incident. Parries further argues that the so-called “last chance agreement” was itself evidence of disparate treatment because it was an unprecedented discipline step that was not countenanced or mentioned by the union contract. Not surprisingly, however, the district court found that the agreement actually benefitted Parries because it was in lieu of immediate termination and thus could not be used as evidence of negative disparate treatment. The existence of the “last c hance” warning did not insulate Makino from arbitration; Parries requested arbitration after being fired under the “last chance agreement” and won. Notably, although Parries succeeded in his effort to attain reinstatement, the arbitrator’s order included a stat ement to the effect that the arbitrator had given “no weight or substance to any claim of racial discrim ination.” This determination squares with the district court’s finding that the plaintiff fail ed to show disparate treatment in any of the disciplinary steps leading up to his 1999 termi nation and thus has not made out a prima facie case of racial discrimination with regard to that action by Makino.- 11 - We conclude that Parries likewise failed to make out a prima facie case for his 2001 termination under the four McDonnell Douglas elements. He undisputedly met the first three elements but, as with the 1999 claim, did not adequately demonstrate that he was replaced by a non-minority pers on. When Parries was fired in 2001, his duties were split between two existing workers, both white, who were on a lo wer union labor grade. Eight to ten months later, Makino promoted one of these employees, Greg Waites, to the higher labor grade position Parries had formerly o ccupied. “Spreading the former duties of a terminated employee among the remaining empl oyees does not constitute replacement” and, hence, the question is whether the del ayed promotion of Waites constituted replacement. Majewski v. Automatic Data Processing, Inc. , 274 F.3d 1106, 1115 (6th Cir. 2001) (quoting Lilley v. BTM Corp. , 958 F.2d 746, 752 (6th Cir. 1992)). The record indicates that Waites took on many, but not a ll, of the plaintiff’s duties without any initial change in position or employment status. Thatfact, together with t he substantial delay in Waites’s promotion, suggests that Waites wa s not promoted to “replac e” Parries directly. We cannot say that the district court erred in concluding that the plaintiff has failed to demonstrate that promoting Waites after a long delay was tantamount to replacement.

As an alternative to the fourth McDonnell Douglas element, Parries attempted to show that the second termination resulted from disparate treatment. In June 2001, Parries was fired after engaging in a heated discussion with supervisors Morris and Hoerlein and calling Hoerlein a liar who needed to “get so me balls.” Under the union collective bargaining agreement, Makino could terminate em ployees for offenses of “a serious nature,” including insubordinati on, even if the employee has no prior disciplinary problems.- 12 - Parries argued that the “get some balls” stat ement was common shop talk and did not merit termination, but he presented no evidence of fellow employees making similar comments to management. Parries also argued that, even if the final termination incident showed no disparate treatment, Makino unfairly disciplined him in several incidents preceding his discharge. Unlike the situation leading up to his 1999 terminat ion, Parries was not explicitly placed on escalating levels of discipline, but his discipli nary history clearly did play a role in Makino’s decision to fire him in 2001. Even when t hese prior incidents are considered, however, they do not support an allegation of disparat e treatment. In November 2000, supervisor Hoerlein suspended Parries for five days as a re sult of his being away from his workstation without permission. This suspension was subsequently rescinded and Parries was given back-pay, but he received a written final warni ng informing him that he was in violation of the “last chance agreement.” Farmer, a whit e co-worker who was with Parries away from the workstations, was given only a documented verbal warning placing him on discipline level one. Farmer was not similarly situat ed, however, because Farmer did not have the history of disciplinary problems that Parrieshad and was not subject to a “last chance” warning. Hile, another white co-worker under H oerlein’s supervision, testified that he was out of his work area on the sa me day but was not disciplined. Hile claimed that someone, he could not remember who, told him that Hoerlein had been looking for him and knew he was away from his work stat ion. There is no non-hearsay evi dence, however, that Hoerlein had knowledge of Hile’s infraction and, thus, no proof that Hile was similarly situated to Parries.- 13 - In December 2000, Parries was suspended for three days afte r tape recording a meeting with management. Parries claim ed his punishment was unduly harsh, but he provided no evidence of other similarly-sit uated employees being treated differently. In January 2001, Parries was disciplined more harshly than some white co-workers for improperly recording his hours but, again, fail ed to supply evidence that the co-workers were similarly-situated in terms of disciplinary history, supervisor, or severity of misconduct. Even if Parries had made out a prima faci e case for his two terminations, he did not provide sufficient evidence to show that Makino’s reasons for the terminations were pretextual. “Once a plaintiff establishes a pr ima facie case of discrimination, the burden shifts to the defendant to rebut the presumpt ion of discrimination by providing evidence showing that the plaintiff was terminated fo r a legitimate nondiscriminatory reason.” Smith v. Leggett Wire Co. , 220 F.3d 752, 758-59 (6th Cir. 2000). Because Makino presented a race-neutral reason for firing Parries, i.e., his history of disciplinary problems, poor performance, and insubordination, Parries was required to “produce sufficient evidence from which the jury [coul d] reasonably reject the employer’s explanation.” Manzer v. Diamond Shamrock Chems. Co. , 29 F.3d 1078, 1083 (6th Cir. 1994) . To make a showing of pretext, “the plaintiff is required to show by a preponderanc e of the evidence either (1) that the proffered reasons had no basis in fact, (2) that the proffered reasons did not actually motivate his discharge, or (3) that they were insufficient to motivate discharge.” Id. at 1084 (citations omitted). Parries did not challenged the factual accuracy of the disciplinary infractions and thus did not disput e pretext under the fi rst manner of showing. In order to show pretext via the second method, “the plaintiff may not rely simply upon his- 14 - prima facie evidence but must, instead, introduce additional evidenc e of . . . discrimination.” Id. at 1084. However, the record does not re flect the production of admissible evidence above and beyond that required for a prima facie showing. The third manner of showing pretext “ordinarily consists of evidence that other employees . . . were not fired even though they engaged in substantially identical conduct.” Id . Given that Parries could not demonstrate disparate treatment, he did not satisfy the third method because he failed to show that any other employ ee who engaged in the same pattern of infractions was not fired. See Warfield v. Lebanon Corr. Inst. , 181 F.3d 723, 730-31 (6th Cir. 1999) (holding that an employee fired for a se ries of incidents alleged to c onstitute misconduct must show that a similarly-situated empl oyee engaged in a comparably serious series of bad acts, not merely similar individual acts).

We conclude that Makino’s motion for summary judgment was properly granted because Parries did not establish a prim a facie case of discrimination based on circumstantial evidence, nor did he rebut as pretextual the em ployer’s legitimate business reason for discharge. B. The District Court’s Ruling on the Defendant’s Motion to Strike In addition to attempting to demonstrate an inference of discrimination under the McDonnell Douglas and Mitchell standards, Parries also ar gued that there was direct evidence of racial animus underlying the 2001 termi nation. A plaintiff who can show direct evidence of discriminati on need not show the four McDonnell Douglas elements or satisfy the Mitchell disparate treatment standard. See Talley , 61 F.3d at 1248. Tomeet his prima- 15 - facie burden in this manner, however, the plainti ff must present “credible, direct evidence of discriminatory animus,” and the lower court must then specific ally make a finding that the plaintiff’s evidence is credible. See id. In an attempt to produce such evidence, Parries proffered an unsworn declaration by a former Makino employee, Brian Smith, who claimed to have heard supervisors Ed Morris and Patrick Ruggiero use the term “nigge r” in reference to Parries while he was under their supervision. Howe ver, the Smith declaration fails to indicate when the statements were made and under what circumstances. Mo reover, the document was filed after discovery was complet ed, and it was not covered bythe description of Smith’s expected testimony as summarized in the plai ntiff’s witness list, filed pursuant to Federal Rule of Civil Procedure 26. In response, Makino filed a timely motion tostrike Smith’s declaration, pointing out that the plaintiff had “failed toproperly disclose the subject matter of Mr. Smith’s testimony in violation of his obligations under [Rule] 26 and this Court’s Scheduling Order.” The district court did not rule on t he merits of this motion explicit ly. However, in ruling on the summary judgment motions, the court announced that it was not relying on the Smith declaration. Under these circum stances, we interpret the distri ct court’s ruling as an implicit grant of Makino’s motion to st rike, based on a determination t hat the declaration was not filed in a timely manner. While the better pr actice would have been to rule explicitly, we cannot say that the district court committ ed an abuse of discretion in this regard. See Wimberly v. Clark Controller Co. , 364 F.2d 225, 227 (6th Cir. 1966).- 16 - C. The Retaliation Claim In addition to his discrimination claims, pl aintiff brought a Title VII retaliation claim against defendant Makino. “To make a prima faci e case of Title VII retaliation, a plaintiff must prove: (1) he engaged in activi ty protected by Title VII; (2) this exercise of protected rights was known to defendant; (3) defendant ther eafter took adverse employment action against the plaintiff; and (4) there was a caus al connection between the protected activity and the adverse employment action.” Ford v. Gen. Motors Co. , 305 F.3d 545, 552-53 (6th Cir. 2002). Notably in this case, Sixth Circu it precedent provides that “[t]he burden of establishing a prima facie case in a reta liation action is not onerous, but one easily met.” Nguyen v. City of Cleveland , 229 F.3d 559, 563 (6th Cir. 2000). Makino does not dispute that Parries has show n the first three elements of this test. Makino knew that Parries filed a claim ofdiscrimination with the Ohio Civil Rights Commission in the wake of his 1999 termination, and Maki no then terminated Parries’s employment in June 2001. The question remain ing is whether Parries has shown sufficient evidence to raise a genuine issue of material fa ct as to the causal connection between his filing of the civil rights clai m with the Ohio commission and his discharge. To establish the causal connection required by the fourth prong, a plaintiff must “put forth some evidence to deduce a causal connection between the retalia tory action and the protected activity and requiring the court to draw reasonable infer ences from that evidence, provided it is credible.” Nguyen , 229 F.3d at 566 (quoting EEOC v. Avery Dennison Corp. , 104 F.3d 858, 861 (6th Cir. 1997)). In making this determinati on, the court must viewthe evidence in the- 17 - light most favorable to the non-movant and must draw all reasonable inferences in the nonmovant’s favor. See Ford , 305 F.3d at 555. The allegedly retaliatory behavior against Pa rries began almost immediately after his reinstatement at work in August 2000. The Sixth Circuit has found timing to be a relevant factor in a showing of causal c onnection. “Although ‘tempor al proximity alone will not support an inference in the fa ce of compelling evidence’ to the contrary, ‘the proximity in time between protected activity and adverse employment action may give rise to an inference of a causal connection.” Ford , 305 F.3d at 554-55 (quoting Moon v. Transp. Drivers, Inc. , 836 F.2d 226, 229 (6th Cir. 1987)). The relevant measure of time is the period between the resumption of work after t he protected activity and the termination. See Ford , 305 F.3d at 554-55. In Harrison v. Metropolitan Government, 80 F.3d 1107, 1119 (6th Cir. 1996), we held that a 15-month time gap was short enough to constitute “temporal proximity.” Here, Parries wa s fired by Makino less than 11 months after resuming his employment. Further, Parries claimed that t he first retaliatory behavior occurred on August 16, 2000, a mere eight days after he returned to work. As the district court noted, however, in order to show causal connection, a plaintiff must demonstrate some evidence of retaliatory conduct in addition to temporal proximity. See Nguyen , 229 F.3d at 566. Although the districtcourt found that there was no such additional evidence in the record, our reviewsuggests that the plaintiff may have been subjected to excessive scrutiny of his conduct and may have experienced “more frequent disciplinary writeups . . . for trivial matters ” than other Makino employees, which we have held to constitute evidenc e of retaliatory conduct. Moore v. KUKA Welding Sys. , 171 F.3d- 18 - 1073, 1080 (6th Cir. 1999); see also Harrison , 80 F.3d at 1119 (“More important, however, is the fact that study of the record in this case reveals an atmosphere in which the plaintiff’s activities were scrutinized more care fully than those of comparably situated employees. . .”). For exam ple, in August 2000 supervisor Don Hoerlein twice “counseled” Parries for making loud or strange noises while working. Parries c ontends that Hoerlein’s accusations were false, but even if true, the incident suggests that Parries was being disciplined for basically “trivial matters.” In November of the same year, Hoerlein suspended Parries for five days for being away from his work stat ion without permission. Makino later rescinded the suspension and grant ed him back pay, issuing Parries merely a “final warning” as his punishment. We recognize that a jury could find that the close supervision Parries received after his earlier discharge was simply t he result of his history of disciplinary problems leading up to the 1999 dismissal. On the other hand, he was reinstated following post-discharge arbitration, and a jury might find that t he ensuing level of scrutiny leading up to the dismissal in 2001 was unjustified in terms of the relatively minor nature of the alleged misconduct it revealed. Moreover, the plaintiff identif ied another factor that is pertinent to the determination of causal connection in the retaliation se tting, and that is increased workload. See Ford , 305 F.3d at 555. Parries alleged thatsupervisor Ed Morris assigned him a disproportionately high number of the difficult j obs and that this overlo ad in his assignments resulted in Parries’s poor work performance. However, the only evidence to support this- 19 - allegation came from the declaration of Br ian Smith, which, as noted above, was not considered by the district court. Finally, Parries presented evidence that Makino supervisors discouraged the filing of grievances and threatened to take retaliato ry action against employees who filed them. In a memo written by Ed Morris requesting t hat Parries be removed from his supervision or fired, Morris cited Parries’s history offiling grievances as problematic behavior. Similarly, supervisor Hoerlein warned whit e employee Farmer that the company would “take care of the problem” if Farmer continued to file grievances. Although all of Farmers’s grievances and some of Parries’s were not based on race and thus were not protected actions, Parries asserts that this shows a willingness on the part of Makino to punish employees for making grievances. Indeed, we have held that a supervisor’s comments indicating an intent to run employees out ofhis department, combined with the fact that several employees feared retaliation if they te stified at a hearing, sufficiently established a prima facie case of retaliation. See Harrison , 80 F.3d at 1119. While it appears that Parries’s situation was not as compelling as the one in Harrison , we conclude that the two situations are similar enough that Hoerlein’s threats could be considered evidence of retaliation. A finding that the plaintiff has established a prima facie case of retaliation does not end our analysis, however. As wit h a claim of discrimination, the burden then shifts to the defendant to “articulate a legitimate, non-discr iminatory reason for the adverse action.” Abbott v. Crown Motor Co., Inc. , 348 F.3d 537, 542 (6th Cir. 2003). Makino met this burden by establishing that Parries was termi nated due to his history of disciplinary- 20 - problems and his unacceptable insubordination toHoerlein in June 2001. The burden thus shifted back to Parries, requiring him to demonstrate by a preponder ance of the evidence that the proffered reason was a mere pretext for a retaliatory animus. Ibid. We have suggested that “caution should be exercised in granting summa ry judgment once a plaintiff has established a prima facie inference of retaliation,” Singfield v. Akron Metro. Hous. Auth. , 389 F.3d 555, 564 (6th Cir. 2004), but we conclude that in this case, summary judgment was appropriate. We have already held in conjunction with the plaintiff’s discrimination claims that there was insuffi cient evidence to establish pretext. Parries presented no additional evidence to indicate thatthe employer was engaging in pretext in terms of the retaliation claim. It follows that summary judgment was proper on the latter claim as well as the former.

CONCLUSION For the reasons set out above, we AFFIRM the judgment of the district court.
