Accrued annual leave when hours reduce

[EnglishRain]

On mat leave, contract is full time. Accrued 20 days annual leave since being off.

Hoping to go back 0.8 WTE. If I take this leave after my contract changes, 20 days will cover five weeks of annual leave. If I take it now, as a full time colleague, it covers four weeks leave.

Can work change my already accrued leave, ie. reduce it to 0.8WTE entitlement even though it's already accrued on my current full time contract?

I don't know the law but I'd imagine not. That was just my annual leave balance for the rest of that annual leave year. I put it on the end of my mat leave

I wouldn’t think so.
I added mine into end of mat leave and got couple months full pay before going part time

No you've already accrued it.

No they can’t. I’ve changed hours a few times. They might ask you to take some in advance of the change, which I have done (eg by going down to 3 days a week, but using up leave by staying on FT pay).

It works to your favour - you accrue at full time and can take it over your new PT pattern.

It is/was accrued during your ft contract so you have already earned it. I had accumulated 10 days which translated into 20 pt days when I went 0.5fte. Can you get them to calculate in hours? My office managers attitude improved a lot when instead of 20pt days off she was dealing with 80 hr of leave

This is great news, thanks all.

I am already taking a month of annual leave, but I've got another 20 days accrued too. What I would like to do is go back 0.8WTE but work three days for a while using my fourth day as annual leave. Just feel like I will get more out of the extra time with DD being spread out. And might help ease me back into work slowly...

You can do that, that’s exactly what I did after returning from May leave with my DD working 3 days instead of contracted 4, I’m currently on Mat leave with DS and will be doing the same thing when I return to work in Jan
