No worker in the US should be held hostage to unions period, compulsory union dues are unconstitutional under the first and 14th amendments, and the unions need to be stripped of their ability to steal money from workers paychecks on a national level.
If the workers love unions so much they will be happy to voluntarily send them dues, there nothing patently illegal about a POTUS issuing an executive order immediately ending withholding of union dues nationwide, and ordering the National Labor Relations Board to get a Federal Court Order enforcing the Presidents decision
Lets fight it out in the courts, and lets make it a campaign issue, with the promise to end compulsory withholding of union dues one of the first acts of the new GOP Administration.
Its stupid to allow the left(Communists) to use the same mechanism the IRS uses to fund themselves.
