AIBU to feel annoyed about this work situation

[user140917392]

I recently spoke to my manager about reducing my hours at work after returning from illness and struggling to get back to my hours after a phased return. I found that I wasn't able to cope with a 9-5 day and asked to work 9-2.
He agreed and told me that once he returned from his holiday (this week) he would change my contract.
He called me up to his office today to tell me he can't change my hours. One member of staff has handed her notice in so we will be short and some members of staff are complaining because I won't be working Saturdays as two staff are needed all day on Saturdays and I can't work a full day.
AIBU to feel annoyed?

If your colleague only just handed in their notice, surely they are there for another month at least, possibly another 3mths pending their notice period? I know its early days, and their resignation should have no baring, but do you think you will ever be able to return to full time hours?

If the colleague leaves in 1mth, could you do part hours this month and increase them whey they leave? Pending you being well enough of course. Would a job share work at all?

Your boss doesn't sound understanding, but he/she also need a way to get business done. I'd have a few plans B and C as options to give them.

They have 2 weeks left at work and 2 weeks holiday. I have explained that I don't see myself been able to return to full time hours. I did suggest a job share and offered to work 9-1 and the job share do 1-5 to make it equal hours for both.

You are therefore entitled to request a reasonable adjustment.
