I returned from maternity from having my first child in 2020 and requested flexible working for 24 hours per week. This was agreed after initially my manager refusing but HR stating there was no reason to refuse my reduced hours. Because I had reduced my hours my manager said I now had to job share and the lady who had covered my maternity leave would be staying on full time. It was agreed we would both do 18.5 on the job and the remaining hours we would work on project work. Only 5.5 per week for me and 50% of her hours on project work.
I got pregnant again in 2022 and had my DC and have returned to work today from having a year on maternity leave. My job share covered my post whilst on maternity leave and the project hours were not covered.
My manager said today that if I'm on leave then my job share has to cover my hours (as she is full time). This means if she’s on leave I can’t take leave. I said are we not job share? And my manager said we are job share but my hours have to be covered whilst I'm not here. I can’t cover my job shares hours as I’m part time, so her hours aren’t covered if she’s on leave the beginning of the week.
I feel a bit upset about this. Am I overreacting?
