Ok so I'm doing an internship for pharmacy and I have amanager who can be very aggressive one day (verbally abusive) and then very nice the next as if nothing happened .It keeps going in cycles like this. I have tried to talk to him but it doesn't do much. For the past week he has been in a happy nice mood. I currently got offered an internship place by a family friend who heard about my situation however I am unsure what to do as I have 4 months left with my current job before my internship finishes. Should I stay or change?
