yeah idk what exactly is happening but it's not good
maybe she thinks she can abuse you without any consequences, but can't do that with other people for some reason
it's not ok to get screamed over plastic buckets or simple mistakes and might eventually make you feel like it's not ok to speak up or make mistakes
if she doesn't do that in front of other ppl then try not to stay alone with her
if you can talk back and set boundaries without consequences then do that
if possible try to bring it up with your management or peers
so yea we support u
