So many wrong answers here. I have coworkers leaving in droves. It has nothing to do with the union. Zero percent. It really isn't about parents at board meetings. Teachers are oddly removed from board meetings.
The reason teachers are leaving is because the workload is unbearable. 95 is right. Admin continues to pile more on our plate and teachers burn out fast. Additionally, the parents are allowed to speak to teachers however they want, and they are given free reign. Parents tell us that their kids are gonna pass, so we are told to make it happen. The kids do nothing, and we have to either dumb down the work to a ridiculous level or change the grades to reflect work they didn't actually do. Discipline and structure are gone. Districts lie about fights, drugs, suspensions, etc to keep their reported numbers low. This puts teachers in an impossible position because it completely undermines our ability to hand out meaningful consequences.
In short, teachers are leaving because they are not supported. Not by parents and not by admins. Children are allowed to walk all over us. Sorry for the political comment, but this became a popular way to treat teachers when Chris Christie publicly bashed us for his entire term after saying he'd be a friend to teachers during his campaign.
