Weird assistant manager

Jaime

So at work we got this new assistant manager a while ago. Where I work they have cameras in front and around some parts of the store. So the assistant manager was saying I need you to price so in the morning we have some more bins for donations. I said ok I can do that and he was telling me were to leave the bins once I am done then he said I’ll watch you through the camera and pointed to the one that’s in our back room where we price and run donations. To me the way he said it was so creepy and weird and made me feel uncomfortable. This isn’t the first time he has something that wasn’t ok. He said to me once since you’re a girl you can organize it really well. When I told my manager that he said that comment she defended him and said not to take it as a sexist comment. What do you guys think?
