Where/How can I report inappropriate work place behavior in an establishment that doest have a true HR department?

not unless th 'behavior' is illegal.

They have a right to run their business how they see fit, unless they are doing something criminal.  Making you uncomfortable - you don't report that.  If you don't like the job, quit.  Find a job you do like.

Unless it's criminal, in which case you'd report it to the police, there's no one to report it to. If it violates civil law, to get legal satisfaction, you have to sue them. That's not reporting it, though. There's nobody whose job it is to go and scold your employer for making you feel uncomfortable.

Maybe instead of being a snitch, you can just tell them what they’re doing that makes you uncomfortable and politely ask them to stop?

you know, maybe you can act like a normal person that’s not a snake that bites the hand that feeds?

Literally nobody likes snitches
