The only benefit from staying in teaching is 1. Decent pension, well above private sector. Big bonus.
2. Security.
3. Liking the job 70% of the time. Not many people can say they love it 100% time.
Downside.
1. Stress
2. Lack of respect from pupils in some sercumstances.
3. Hours.
4. It's hard work.
You need to way up everything before changing.
I have always had the philosophy that if you are stressed out and not happy then change tack.
Maybe look at another job in the same sector or another job in the public sector.
If this does not fit then do what you think will give you security and happiness....like going back to the glass
All the best in your decision.
