For all of my feminists out there

Our drama director at our school is being sexist and he was saying stuff when we were carrying in wood for the sets like "we need some boys for the heavy lifting" and we can move past that because he's older so maybe it's just a generational thing but I was talking to this person today who is in stage crew like me and she said that she was told not to come to certain after school things to build the sets because they weren't doing it that day but she goes anyway (because they actually were and he was lying) and he's like "oh"

A lot of the girls are laughing it off but one of the teachers we were talking about this with says we should definitely report him

What do you think?
