After being on both sides (worked as a teacher and now working elsewhere with some days wfh), I feel that being a teacher is physically and emotionally tiring but working elsewhere can be more taxing cognitively. Teaching is actually quite nice and not that tough (not that tough to do well also) BUT what isn’t that nice about teaching is that there is no flexibility in taking leave. While there are provisions for urgent leave, you cannot suddenly decide that you need a break and would want to take AL. This is why at my current stage of life, I want a job that offers me the flexibility of taking leave whenever I want.
