Quitting the union is like breaking up with a clingy girlfriend. No matter how clear you make it that the relationship is over, they will always say that theyisheard you or that you aren't thinking clearly.
Probably to fund the second-rate failed defense attorney they hired as a contract lawyer.
The only "repercussions" are headaches you'll get TRYING to quit. Had a co-worker take at least three years to quit because the union kept giving her the runaround. You have to send in a letter outlining your intention to withdraw at a specific date from your "anniversary" and must be sent to multiple people at various levels of management and organization.
