Text: A district court’s decision to grant a preliminary injunction under the RLA rests within that court’s sound discretion. Adams v. Fed. Express Corp., 547 F.2d 319, 322 (6th Cir. 1976) (citing Virginian Ry. Co. v. Sys. Fed’n No. 40, 300 U.S. 515, 551 (1937) and other cases). We do not disturb an order of injunctive relief unless we conclude that the district court abused its discretion in issuing the order, id., and a court abuses its discretion if it relies on clearly erroneous factual findings or improperly applies the law. Smoot v. United Transp. Union, 246 F.3d 633, 648 (6th Cir. 2001). We review de novo the district court’s legal determination of whether a labor dispute is “major” or “minor” under the RLA. CSX Transp., Inc. v. United Transp. Union, 395 F.3d 365, 368 (6th Cir. 2005).
