Post pregnancy work worry

I have a week left of work before I go on maternity leave, yey!! I’ll be coming back to work full time though. But they can’t guarantee that I’ll be working with the same (very lovely) manager unfortunately, but I will be put somewhere in the business, which is great. I’m just worried I’ll be put under management of this one person in particular who has a god complex going on... mainly through overlooking people below and generally manages in not a very tactful way. My brief encounters with working together have left me with a slight worry of the possibility of working in that area when I return. 😏 I’m sure this person is humane outside of work, but just a “spikey” manager.... I’ve now come home anxious over our encounters because of it... once baby is here I won’t even be thinking about this...! I’m sure you ladies also worry about work related maternity things!! Just needed to unload as I’m stressing...
