(1)
It is an unfair labor practice for an employer, individually or in concert with others, to:
(a)
Interfere with, restrain, or coerce his employees in the exercise of the rights guaranteed in section
8-3-106
;
(b)
Initiate, create, dominate, or interfere with the formation or administration of any labor organization or contribute financial support to it; except that an employer shall not be prohibited from reimbursing employees at their prevailing wage rate for time spent conferring with him, nor from cooperating with representatives of at least a majority of his employees in a collective bargaining unit, at their request, by permitting employee organizational activities on employer premises or the use of employer facilities where such activities or use create no additional expense to the employer;
(c)
(I)
Encourage or discourage membership in any labor organization, employee agency, committee, association, or representation plan by discrimination in regard to hiring, tenure, or other terms or conditions of employment; except that an employer shall not be prohibited from entering into an all-union agreement with the representatives of his employees in a collective bargaining unit if such all-union agreement is approved by the affirmative vote of at least a majority of all the employees eligible to vote or three-quarters or more of the employees who actually voted, whichever is greater, by secret ballot in favor of such all-union agreement in an election provided for in this paragraph (c) conducted under the supervision of the director. Where the collective bargaining unit involved is currently recognized under sections 8 or 9 of the "National Labor Relations Act", as amended, (49 Stat. 449; 61 Stat. 136), or where the collective bargaining unit involved is currently recognized by reason of certification by the director or the national labor relations board, or where such units were so recognized at the time of an election provided for in this paragraph (c), there is and shall be deemed to have been no need for a certification election as a precedent to an election provided for in this paragraph (c) in such collective bargaining unit on the issue of an all-union agreement. The employees in such a recognized or certified unit within this state shall be the only employees eligible to vote in an election provided for in this paragraph (c) held in such unit.
(II)
(A)
Any agreement as defined in section
8-3-104
(1.5) between an employer and a labor organization in existence on June 29, 1977, which has not been voted upon by the employees covered by it may, by written mutual agreement of such employer and labor organization, be ratified and upon such ratification shall be filed with the director. Any agreement as defined in section
8-3-104
(1.5) between an employer and a labor organization in existence on June 29, 1977, which has not been ratified and filed, as provided in this subsection (1)(c)(II), shall not be legal, valid, or enforceable during the remaining term of that labor contract unless and until either the employer, the labor organization, or at least twenty percent of the employees covered by such agreement file a petition upon forms provided by the division, demanding an election submitting the question of the all-union agreement to the employees covered by such agreement and said agreement is approved by the affirmative vote of at least a majority of all the employees eligible to vote or three-quarters or more of the employees who actually voted, whichever is greater, by secret ballot in favor of such all-union agreement in an election provided for in this subsection (1)(c) conducted under the supervision of the director.
(B)
Upon filing of such instrument of ratification with the director, the director shall certify that such agreement complies with the provisions of section
8-3-104
(1.5) notwithstanding the absence of any other election requirements of this article 3, and by virtue of such ratification and certification, such agreement shall be deemed legal, valid, and enforceable to the extent permitted under the provisions of this article 3, subject to the provisions of subsection (1)(c)(II)(D) of this section.
(C)
Within two weeks after the certification by the director provided for in sub-subparagraph (B) of this subparagraph (II), the employer which is a party to such agreement shall post or give written notice to all employees covered by such agreement on the date of ratification of the fact that the agreement has been ratified and certified pursuant to the provisions of this subparagraph (II) and of the right of such employees to file a petition demanding an election as provided in sub-subparagraph (D) of this subparagraph (II). Proof of giving of notice shall be filed with the director within twenty days after the certification by the director provided for in sub-subparagraph (B) of this subparagraph (II).
(D)
Within forty-five days after the certification by the director provided for in sub-subparagraph (B) of this subparagraph (II) twenty percent of the employees covered by such agreement may file a petition, upon forms provided by the division, demanding an election submitting the question of ratification of such agreement to the employees covered by such agreement. If ratification of the agreement is approved by the affirmative vote of at least a majority of all the employees eligible to vote or three-quarters or more of the employees who actually voted, whichever is greater, in said election, the agreement shall be conclusively deemed ratified. Such election shall be held as promptly as possible following the filing of the petition. In the event that a certified contract expires or is terminated prior to the conducting of such an election, such certification shall be applicable to any subsequent agreement between the same parties until such election may be held.
(III)
The director shall declare any such all-union agreement terminated whenever:
(A)
He finds that the labor organization involved unreasonably has refused to receive as a member any employee of such employer, and any person interested may come before the director, as provided in section
8-3-110
, and ask the performance of this duty; or
(B)
The employer or twenty percent of the employees covered by such agreement file a petition with the director on forms provided by the division seeking to revoke such all-union agreement and, in an election conducted under the supervision of the director, there is not an affirmative vote of at least a majority of all the employees eligible to vote or three-quarters or more of the employees who actually voted, whichever is greater, in such election by secret ballot in favor of such all-union agreement. Such petition may only be filed within a time period between one hundred twenty and one hundred five days prior to the end of the collective bargaining agreement or prior to a triennial anniversary of the date of such agreement, and the division must complete said election within sixty days prior to the termination or triennial anniversary of said collective bargaining agreement. The director may conduct an election within a collective bargaining unit no more often than once during the term of any collective bargaining agreement or once every three years in the case of agreements for a period longer than three years.
(IV)
The director shall provide a means by which employees may submit confidential petitions for an election under this paragraph (c), a means for verifying the employment, status, and eligibility of petitioners, and a means for determining the sufficiency of such petitions with respect to the twenty percent signature requirement, all of which shall be accomplished without disclosing the identification of such petitioners, except as allowed under subparagraph (V) of this paragraph (c). This duty shall apply to petitions filed pursuant to subparagraph (II)(A), (II)(D), or (III)(B) of this paragraph (c).
(V)
No officer or employee of the division shall disclose the names of any signers to a petition or disclose how any person voted in an election to any person outside the division except pursuant to a court order or subpoena issued by a governmental authority or a court, and any such officer or employee who violates such nondisclosure provisions or who refuses to call an election pursuant to this paragraph (c) or prevents or conspires to prevent such call of an election commits a class 2 misdemeanor and shall be punished as provided in section
18-1.3-501
, C.R.S.
(d)
Refuse to bargain collectively with the representatives of his employees in any collective bargaining unit; except that where an employer with reasonable cause files with the division a petition requesting a determination as to bargaining unit representation, he shall not be deemed to have refused to bargain until an election has been held and the result thereof has been certified to him by the director;
(e)
Enter into an all-union agreement except in the manner provided in paragraph (c) of this subsection (1);
(f)
Violate the terms of a collective bargaining agreement, including an agreement to accept an arbitration award;

(h)
Discharge or otherwise discriminate against an employee because he has filed charges or given information or testimony in good faith under the provisions of this article;
(i)

8-2-110
;

It is an unfair labor practice for an employee, individually or in concert with others, to:
(a)
Coerce or intimidate an employee in the enjoyment of his legal rights, including those guaranteed in section
8-3-106
, or to intimidate his family or any member thereof, picket his domicile, or injure the person or property of such employee or his family or of any member thereof;
(b)
Coerce, intimidate, or induce any employer to interfere with any of his employees in the enjoyment of their legal rights, including those guaranteed in section
8-3-106
, or to engage in any practice with regard to his employees which would constitute an unfair labor practice if undertaken by him on his own initiative;
(c)
Violate the terms of a collective bargaining agreement, including an agreement to accept an arbitration award;

Refuse or fail to recognize or accept as conclusive of any issue in any controversy as to employment relations the final determination, after appeal, if any, of any tribunal having competent jurisdiction of the same or whose jurisdiction the employees or their representatives accepted;
(e)
Cooperate in engaging in, promoting, or inducing picketing, boycotting, or any other overt concomitant of a strike unless a majority in a collective bargaining unit of the employees of an employer against whom such acts are primarily directed have voted by secret ballot to call a strike;
(f)

(g)
Engage in a secondary boycott, or to hinder or prevent, by threats, intimidation, force, coercion, or sabotage, the obtaining, use, or disposition of materials, equipment, or services, or to combine or conspire to hinder or prevent, by any means whatsoever, the obtaining, use, or disposition of materials, equipment, or services;

It is an unfair labor practice for an employee, individually or in concert with others, or for a labor organization or any of its agents to:
(a)
Induce or encourage the employees of an employer to engage in a strike or concerted refusal in the course of their employment, or by any means to force or require an employer or any one or more employees to refrain from or prevent the use of any material, device, tool, or equipment intended or calculated to reduce the cost of the work;
(b)

Impose on any employee any fine, penalty, or forfeiture because such employee has used, is using, or has attempted to use a labor-saving device;
(d)
(I)
Engage in or induce or encourage employees of any employer to engage in a strike or concerted refusal in the course of their employment to use, manufacture, process, transport, or otherwise handle or work on any goods, articles, materials, or commodities or to perform any service where an object thereof is forcing or requiring any employer to assign particular work to employees in a particular trade, craft, or class rather than to employees in another labor organization or in another trade, craft, or class unless such employer is failing to conform to an order of the director or certification determining the bargaining representative for employees performing such work; but nothing contained in this subsection (3) shall be construed to make unlawful a refusal by any person to enter upon the premises of any employer (other than his own employer).

(e)
With regard to the entirety of this subsection (3), the following shall apply: Such material, device, tool, or equipment is germane to the employees' craft and not injurious to the employees' health and safety or the public generally, and nothing in this subsection (3) shall negate the rights of an employer and a labor organization to bargain collectively pursuant to subsection (1)(d) of this section.
(4)
It is an unfair labor practice to do or cause to be done, on behalf of or in the interest of employers or employees, or in connection with or to influence the outcome of any controversy as to employment relations, any act prohibited by subsections (1), (2), and (3) of this section.
