I've been working in a new job as a TA five days a week but want to reduce my hours and only work three days for family reasons. I'm so scared to ask though in case they can't accommodate it and hold it against me for asking. I also haven't completed my probation yet so worried they will kick me out. Can they do this? Should I not ask just in case it causes issues? Obviously I was aware of the hours when I took the job, just wasn't aware of the impact of working five days a week on the family commitments I have. (Was only working two days a week in my last job).
