I work at a nursery three days a week on minimum wage. It's very much a job of convenience and I've recently been offered full time hours. Despite needing the money I've turned it down. I just can't face doing it full time, the thought fills me with dread and I know I'll be miserable. I need two days a week to catch up on jobs and just have breathing space and stay sane. Trouble is certain full time colleagues feel that I should have taken full time hours and I'm letting them down and being lazy (that's what they imply in their comments). I always worked full time prior to having children (doing office work) but since having children and being a sahm for quite a while I seem to have more to do and more of a need to finally have time of my own. Is it lazy and selfish and ultimately unreasonable to feel this way?
