Not only would I retire early, I just did retire at the end of the school year. I liked-but-didn't-love my job; I was good at it, and I liked my workplace and my co-workers, but I didn't like getting up before the crack of dawn, and the work had steadily become more and more over the years. And micromanagement has become a big problem over the last couple years.
Why did I retire when I did? I was at the top of the pay scale and "had my years in", so neither my paycheck nor my pension would ever grow larger. My pension is about half of what I was earning working full-time. I can substitute, but it'll be on my terms -- if I have a trip planned or I just plain don't like teaching a certain classroom, I can say no. And although I'll be back in the school, seeing my old friends, I won't have to plan lessons, call parents, or do anything except supervise today's class. I see it as a win-win.
I don't feel completely retired yet. I'm used to having summers off -- I think it will hit me in the fall. However, I already feel more relaxed. It occurred to me that I haven't really "been off work" for 30 years; that is, as a teacher -- even in the summer -- you're always thinking about your upcoming classes, always considering lessons that you could improve. It felt strange at the end of the school year NOT to be prepping /copying the first two weeks' lessons for August. If I were young and choosing a career path again, I'd choose a job that allows for real time off /not just time away.
For many people, health insurance is a big part of this equation -- maybe the biggest part. I have friends who earn more than me /have saved over the years, but who say they have to stay at work for the insurance. I feel fortunate that my own insurance is $25/month until I am old enough to qualify for Medicare; and I can cover my husband, but his insurance takes 20% of my pension -- ouch. I'm going to get a big raise the year he turns 65!
