I am currently on maternity leave and have just been told that I have a new line manager. Instead of reporting to a member of the executive management team I am now reporting to someone who (prior to my maternity leave) I used to work with, as a colleague at the same level. He is then reporting to my old line manager so they have added a level between me and my old line manager. They haven't changed my role description or salary (yet) but I am not best pleased as I have effectively been demoted. What are my rights? Can they do this?
