I think this is probably perfectly legal and also really common but just wanted to check. I'm going back to work later this year after mat leave, and have asked to go down to 3 days a week. They've agreed, but have said I will only be paid 0.52 fte as they can only timetable me for a certain number of periods which works out about half that a full timer does. So I suppose I'll have trapped time where I have little choice to be in school but am not paid for. I have asked for one day to be an early start/finish as technically I'm only being paid to work 2 and a half days a week, but they've said it's unlikely the timetable will allow this.
Do I have to put up with this? Seems so wrong that I have to pay for childcare when I'm not being paid to be at work.
