ANDERSON, Circuit Judge: Bowman Transportation, Inc. appeals from the decision of the district court holding that it had violated Title VII of the Civil Rights Act of 1964, 42 U.S.C.A. Â§Â§ 2000e to 2000e-16, by discriminating against women in its hiring for over-the-road (""OTR"") tractor-trailer driving positions. In Case Nos. 84-8105 and 84-8899, Bowman, a trucking company, raises numerous challenges to the district court's findings with respect to the disparate impact of its one-year prior experience rule, the pattern and practice of discrimination against women in hiring for OTR truck drivers, and the certification of the plaintiff class (""plaintiffs""). We reject each of Bowman's challenges. On the cross-appeal, we also reject plaintiffs' challenge to the district court's refusal to include hiring goals in its remedial order. In Case No. 85-8409,1 Bowman argues that the district court's civil contempt order dealing with back pay is punitive, and since civil contempt may not be imposed for the purpose of punishment, the contempt order is invalid. We find no merit in this contention. Thus, we affirm.
