I came back from maternity to 28 hours a week/4 days of 7 hours. On the day off I’m often finding myself answering phone calls or replying to emails, especially at the times that we’re busy. I try to do the bare minimum but there’s something of urgency most weeks. There’s nobody else able to deal with it, we have no on call system in place and I’ve always just got on with it thinking such is the nature of the bussines that a quick reply or action is often needed. We have a flexible system in place which in theory allows for taking those couple of hours off the following day. In reality though it’s rarey possible. Would it be unreasonable to demand a full time pay for part time hours? I don’t mind doing the work but it’s frustrating as it’s unpaid most of the time.
