So I don't know if I need to give my head a wobble or if this is really not on.
I'm retuning from mat leave in a month, I have agreed to a reduction in my work hours with my line manager working approx 80%. I had hoped to work a set three days, then alternate Saturdays and Sundays (works better for my mum and MIL who will be looking after DD). But the company's week starts on a Sunday so some weeks I would work more hours than others, but averaging at the 80%. So I called HR to ask, the person said to email a specific team so I emailed asking will this be OK, knowing that my manager wouldn't know the answer anyway. I also asked what would happen to overtime hours, if and when they arise (company and manager have form for expecting unpaid overtime and the only time I have been paid overtime is when I worked a 70+ hour week and I told them I was pregnant, so another teams manager actually went and spoke to my area manager to get me overtime paid).
Instead of replying to me, they have spoken to my area manager who has spoken to my line manager, who has spoken to me. That's fine, but I've not had an answer to my overtime question, and AIBU to expect HR to at least acknowledge my email and say we'll have to talk to otbers about this is this ok?
