Would you go part time in my position

[bitofadilemma22]

Have name changed as I've included a lot of detail. Am thinking of going down to 4 days a week from a full time high pressure professional role. Am 53 and feel like I just can't do it full time any more. My main concern is that it might compromise my plan to retire at 60. Here are my circumstances:

FT salary of £65.5k
£95K left on mortgage which I'll be able to pay off fully from mine and husband's savings in 5 years
Joint household outgoings of around £1600 which we split 50/50
Mortgage pot ok-ish but need to work on it in the next few years - my plan is to put all of my annual bonus (usually around 10% of salary) into bonus pot every year, which I haven't been doing to date
Support my child (not partner's) at uni with around £250 per month and expect to do so for the next 3 years

Partner earns similar to me but plans to continue working FT.

WWYD in my position?

Sounds amazing. I did this a while back. At the time I tried to make up for less money by saving because I had more time to make better money choices.

That's great OP. I think it'll make a huge difference to your quality of life. Where I work a lot of us work 4 days and it just gives you some breathing space from the busy intense pace of workdays. Every Friday I feel immensely grateful and happy for the freedom it gives me - and I have had Fridays off for 10 years! The novelty never wears off.
