In United Steelworkers of America v. Weber, the U.S. Supreme Court rules that a voluntary affirmative action plan negotiated by a labor union and a private employer, reserving 50 percent of slots in a training program for black employees, does not violate Title VII of the Civil Rights Act. The Court finds that the program is legal because it does not “unnecessarily trammel the interests of white employees,” does not “create an absolute bar to the advancement of white employees,” is temporary, and is designed to remedy past racial imbalances in the steel industry.
