Taking a substantial pay cut for a career change

[Eldermileniummam]

In what circumstances have you / would you consider halving your salary to start a new role?

I'm considering leaving my professional role for a salary of around £75K to teach the subject I'm an expert in for around £30-45K. My job is stressful and I imagine this will be more family friendly hours and less stressful plus I think I'd enjoy it but it is a risk.

I earn as much as I have earned and so it's a bit unappealing to lose so much but there are other perks and my salary would increase over the years.

We can afford it as my husband also earns similar to what I earn now and we could afford the mortgage and bills on one salary at a push.

This is a situation where you need to look at the different types of "wealth." There isn't just monetary/financial wealth & considering how you will gain wealth in the other areas might help to convince you.
There's a good book called The 5 Different Types of Wealth, it's worth a read.

Don't underestimate the stress and long hours of being a teacher in a state secondary school if this is what you mean - look at all the threads here of teachers leaving!

Do at least a couple of weeks work experience in a school first or take a sabbatical from your job and work as a TA before you invest in lengthy stressful teacher training

Could you go part time in your current job? Or work for a diffenrt company eg move to charity or public sector?

If you do something like IT and want to teach IT to adults in a college that's a bit different.

If it is teaching in a state secondary school, DON'T DO IT!

You're not talking about a state school teaching job are you?

“Teach” 🚩 (from one who had this role). Nuff said.
