I work part time in the evenings after looking after our 3 year old and 1 year old by myself since about 5am, then I go to work until 9pm. 3 out of 5 evenings as well as a long shift on a Saturday. I'm also doing a qualification at the moment, which takes up quite a bit of time. On top of a 1 year old that doesn't know what more than 2-3 hours consecutive sleep is, I'm knackered.
However I get harassed weekly by my manager to do more than my contractural hours. If I say no I get the silent treatment and it is really awkward. I hate it so I have ended up saying yes lots recently. He promises people time off without getting the cover first, I get that it needs to be covered but surely that's a massive failure on his part. He also leaves it really last minute, so he says I might need help the week of xyz then when I say ok, let me know ASAP what shifts you need covering and I'll see where I can help. I'll chase it and still nothing until the week or two before and when I've made plans or can't source childcare at such short notice he'll be furious that I can no longer help.
Am I being that unreasonable? I've just said no to working Sunday and Saturday this weekend and dreading my shift this evening.
