A colleague at work has just had a promotion to manager from assistant manager and has since been quite arrogant and I have heard her bitching about staff, has been quite insensitive to one whose grandparent is very unwell in hospital, has asked me why I don’t work a certain day as I only do 4 days, even though this was agreed with the previous manager and most people in my work do 3 or 4 days and I even heard new manager say to someone that they need a day off and it’s fine that they worn 4 days but for some reason it seems they think I should be doing 5. I feel like the new manager is trying to guilt trip me into taking on an extra day or come in on my day off to cover. Which I do sometimes but I have an appointment for blood tests tomorrow and I’m not feeling the best. I’m worried about my role now as she seems to have changed personality now she has become manager. Aibu to feel worried about how this will effect us at work
