While she needs to know what her dad has been doing under her management. But I don't know if it would stop his unwarranted harassment.

He's probably been doing this for some time with barely adult workers by sexually harassing them by wanting to sleep with them, creating a hostile work environment under his daughter's management and her being indirectly responsible for the unwarranted sexual harassment.

I do have a concern of how she would treat you when you tell her about how her dad is making unwarranted sexual comments to you.

She might get hostile towards you that you are accusing her dad of being a predator and might reveal that other girls came up to her about it again that her dad is making sexual comments towards them. Thus creating more of a toxic work environment.
