You are absolutely correct that government agencies are terribly abusive. I was a manager and more than once I had upper level managers order me to do something that violated the contract. I couldn’t disobey a direct order, so I told them they would need them to put that in writing. They backed down.
I know that the four unions whose employees I supervised did not require membership and I haven’t found any union in any federal agency that is compulsory. I don’t agree with compulsory unions and support a national right to work law.
I think teachers unions are harmful to the educational system and should be abolished, along with the Dept. of Education.
Beyond that, the idea of not deducting dues from employees paychecks that have CHOSEN to belong to a union is just harassment. If I were in a union and that passed, I would have my dues auto deducted from my bank account.
You got your “not” flipped in the last sentence?
