I've asked if I can go back to work part time and my work have offered me a different role which would allow them to not split up my old job (although they have done this in the past for another member of my team). The salary grade for the new role is lower than my old one. If I was to be paid the top end of the grade it would not be too much of a drop, but if it was the lower end it would be quite a big difference. I'm just wondering what my rights are (if any)? I've taken the full year off.
