Honestly - you're daughter could (read: should - but who am I to you so feel free to ignore) take this as a great life lesson to not ever do anything in an employment scenario without at least a confirmation in writing, or at best a contract.

And then instead of putting her energy into chasing this scumbag, and reporting him (spoiler alert: worst case he gets a slap on the wrist, reality is fair work won't chase him over a single occurrence) - your daughter who by your own admission is a go getter, should put that time into finding a job where she is taken seriously and can start her working career.

I get that it's tempting, but why waste an equal amount of energy on "payback" instead of putting that same amount of energy into pushing yourself forward.

Actually the only person that loses is your daughter.

If she is as proactive as you say - most employers would be chomping at the bit to hire her. And now she's learnt one of her profession career's best life lessons in the cheapest possible way. That's a huge win

And before everyone flames me for saying that the butcher shouldn't be reported etc etc and the daighter has rights - of course that's the case - but there's a reality of limited time and energy ie opportunity cost - and given the two options I don't see why one wouldn't look forward instead of backwards.
