Sorry if this has been asked before but i can't find an answer anywhere.
Currently on maternity leave and last month decided to apply for a mortgage, for the application i had to ask my work to write a letter explaining when i will be returning and what salary. They were happy to do it and i had no issue asking as i'd always planned to return.
I'm now having second thoughts and don't really want to return. We're moving 2 hours away which i thought would be fine to commute as i did it before children and it never bothered me, but i now realise doing that will mean i basically won't see my baby. I'll have to leave before he wakes up and will be home at his bedtime. It also doesn't make financial sense as i'll spend half my salary on train tickets.
I guess i was just too sleep deprived to think it through and got carried away after finding our dream house.
My question is, do i now have to return to work because i told them in writing that i would? Is that now a legal obligation?
Or can i just give in my notice as usual and just accept they might be a bit annoyed with me for messing them around? The alternive is returning for a week and then giving in my months notice, but i feel like that's a much worse thing to do. I do realise i've made a mistake by messing them around so want to do it in the nicest way possible, but surely it is possible for circumstances to change and people to change their minds.
I only recieved SMP so won't have to pay anything back.
Thanks for reading/ any advice!
