No, it does not. Employees access and emergencies occur where people of any gender need to access a bathroom that isn’t “theirs.” I’d even argue that a locker room, there is an expectation you will be seen and there’s a potential to be accidentally seen. Somebody holds a door open too long, a person goes into a wrong locker room accidentally, you don’t realize the mirror reflects out the door, etc etc.
So no emergencies ever, then? Bathrooms are tied up and people who need a bathroom should just soil themselves? The space should only be accessed, cleaned, maintained, by the employees of the gender of the room?
That is your personal standard and good for you. It is not the universal standard. Exceptions occur, accidents happen.
If being seen naked is that horrendous for you, then you should probably avoid the locker room or use one of the private stalls.
It is not criminal, first off, and secondly, she undignified him by having an expectation that he should not access a bathroom he needs because she opted to change in the open part of the locker room instead of a private part.
If she’s in a private stall, he opens it, takes a good long look, then wanders off? Yep, that’s an issue. But she said he crossed from the bathroom area in front of a doorway with a view to the locker room, did not linger, and saw her while crossing through. He didn’t stop, he didn’t stare, he didn’t take a picture, she didn’t draw her like Jack draws French girls, he left. According to her, not according to him, according to HER.
