How have the courts treated a motion for a preliminary injunction in an employment discrimination case brought by a unionized union?

Appellants claim that the district court erred in various respects, both procedural and substantive. As to the former, appellants argue that the complaint should not have been dismissed on a motion for a preliminary injunction and that they should have been allowed to amend the complaint to clarify that they were the actual victims of prior discrimination. See Watkins v. United Steel Workers of America, Local 2369, 516 F.2d 41 (5th Cir. 1975). On the substantive issues, plaintiffs' principal claim is that the grossly disproportionate layoff of women under section 80 violated Title VII, despite section 703(h).
