From the Pittsburgh Post-Gazette:

A federal judge in Harrisburg has granted a preliminary injunction that bars the Teamsters union from collecting dues from 20 Pennsylvania Turnpike workers in Harrisburg. In a lawsuit filed in March, the Turnpike employees sought the injunction, alleging that a “maintenance of membership” clause has unlawfully prevented them from resigning from the union. The court has not ruled on six Pittsburgh Turnpike workers who also sued the union and Turnpike executives in March, alleging that they had been overcharged for union dues even after they had resigned from the union.
