Sexual harassment

So I work in a kitchen in the US. Two of the managers definitely have the "boys club" "locker room" mindset and are constantly saying and doing skeevy shit at work. They're always talking about the sex acts they'd like to perform on their female coworkers and customers. What really has me worried is that one of them has been cornering one of the young ladies I work with in the break room and touching her without her consent. There hasn't been anything explicitly sexual yet but that's still such a huge and terrifying breach of her autonomy. These things have been brought up to both management and the owners and they got a "talking to." this is clearly not okay and is also clearly not being dealt with. What kind of legal recourse do my coworkers have? These ladies deserve to be safe in their workplace.

(Edited to change "girls" to "ladies." I was unintentionally insensitive, sorry)
