I hear you, OP! I have been teaching for 37 years and have four semesters to go before I retire. Believe me, I am counting down...
A few realities that many in the public just don't know/understand:
summer - Summer break was NEVER four months. In most places it was never even three months. In my district it's seven weeks. And it is not "vacation" -vacation is time off from working, where you still get paid. Teachers aren't paid for the summer, and it's a long haul from the the last paycheck in June to the first one at the end of August.
pension - Old teacher like me have a traditional pension, with a defined benefit. Younger teachers mostly have a defined contribution plan that is second-class at best. The pension is calculated based on your salary, years of service, and age. I started young, so I actually have to work longer, as the years of service aren't as important to the calculation as your age. Retiring under age 60 costs you $1,000-1,800 per month for each year before 60. Retiring before 63 will cost you, no matter what. And most teachers do NOT get medical benefits in retirement. If they have a good contract, they get a small stipend to help pay for insurance until they qualify for Medicare.
discipline - At least in California, school have fallen victim to an insidious philosophy. No, not CRT -but "restorative practices." The real RP program might be great, but not the way it is being implemented. It basically says that a child who misbehaves is really a victim who needs to be restored to everyone's good graces, and given a chance to make amends rather than be punished. Suspension is no longer allowed. I recently had an 11-year-old boy (certainly old enough to know better), fondle a girl's buttocks and breasts, smack another student in the head, and use racial slurs to another in a two-day period. He was called to the office for "counseling" and sent back to class within twenty minutes. That was it. He didn't even lose a recess. The result is that the kids know that nothing really ever happens to them, so they just do what they want. At most, they have to do lip service to apologizing to their victims. And the bad behavior continues and escalates.
abuse from parents - This used to be a pretty rare thing. Now it's daily. At every school board meeting my colleagues and I are called racists, communists, socialists, neo-socialist colonialists (not kidding), child abusers, and more. This year I have received death threats, for christ's sake! Not all the parents are insane, of course -but more and more of them are, and they are increasingly vocal. And the local media loves to give them voice and create even more drama. Last month one parent group actually put a picture of me on their Facebook page along with what they claimed was my salary (God, I wish I made that much money!) and called my a hypocrite because I spoke up at a school board meeting, asking the board to pass along to teachers and other employees the cost of living adjustment that the state already paid them. A COLA is not a raise! It's an attempt to keep up with inflation.
The job of teaching has become nearly impossible. I'm at a great school, have a great principal, and wonderful, supportive colleagues -and I'm still miserable. I'm out the minute I can afford to leave.
