though I agree that the general unions have not made as much, the general government continues to take a fair bit of money, everyone else in government gets a raise, why not the teachers?
Teachers are under paid, this is a common problem, if teachers were paid better, you would have better teachers, the best hospitals have the best doctors because you can afford them, this is why the saying "those who can, do, those who cant, teach" exists. because if you could do something else who would want a thankless, under paid, under supplied job when you could work private sector and make sometimes 2-3 times as much money with the same education, many of todays k-12 teachers are people who can't do anything else either.
teachers used to be better, because there was a glass ceiling that kept intelligent women out of better jobs, so the education system gave them a job that was way beneath their ability, but a job that paid and helped put money in the bank, they were treated like second class citizens and unfortunately this feeling hasn't changed, and as a job that now has alot of legal exposure (arguably as much as most way better paid medical staff considering the sue-happy way of things anymore) and alot of time on and off site invested, its a terribly thankless job.
