I'm 35. I have two DC and DH. I am not the only earner in our home, but I am the higher earner. We have a joint mortgage.
I have worked FT all my life when not in education. I'm often tired, and struggle with my MH.
I currently work around 40 hours over 5 days. If I were to drop to a 4 day week, it would make a £500 difference per month. This is currently the amount we try to save each month (and often gets pulled back out for car, home maintenance, etc).
If you were in my position, would you do it?
