Even when you get out of the union, they try to pull you back in:
The case involved nine workers for a Brooklyn condo complex who voted unanimously on Sept. 26, 2012, to get rid of United Workers of America Local 621 as their bargaining representative. The following week, the workers individually sent the union letters announcing that they "elected to terminate any and all such membership obligations" with it.You owe, you owe, even if you told them no...
However the NLRB did not officially recognize the decertification vote until Oct. 11, 10 days after the union received the workers' letters. On the basis of that, Local 621 claimed it never received proper termination letters. The union was able to get the workers' employer to continue to deduct membership dues from their paychecks for another full year after they had voted to get rid of it.
