This is all about campaign funding and nothing else. Break up the unions and you take away Democratic money to counteract the huge amount of corporate funds allowed by the Supreme Court ruling.
Just on a personal note. I began teaching in 1970 with a $4,800 salary. After my first year we asked for a 2% raise.It was denied. The next year also denied. What teachers and other public employees found out is that cities and states WILL NOT bargain in good faith if they don't have to.People do not want to pay for services never have, never will period.
