I normally work 4 days per week; Saturdays and Sundays, plus two days during the week. This cuts down the cost of childcare for us as we only need it on the 2 weekdays I work.
Due to staff holidays and a couple of longterm sicknesses, I have been told by my supervisor that I must work 7 days a week for whole of January. Apart from the fact that I don't wish to do it as I'll be exhausted, I have absolutely zero childcare to enable me to do this. I might be able to get my parents' to cover the odd day but that's about it. My supervisor wouldn't listen to reason at all and her suggestion what that my DH (who earns far more than me) took unpaid parental leave to cover the month so that I can work.
I am generally very flexible. I work extra hours after my shifts if necessary, and will try to cover the odd day at short notice if at all possible, but I think this is very very unfair.
I know about the working time directive law, but if I don't do as I'm told then I can imagine my work time won't be very pleasant. The supervisor is very prickly anyway and has a lot of mood swings.
Feel between a rock and a hard place tbh.
