Hmmm. Seems to me he DID flash her without asking. A subordinate. And it WAS in his bedroom.
Inappropriate, but not assault IMO.
If he walked into her office at work and showed her his
****, then obviously that's completely unacceptable.
If you're in somebody's bedroom after a night of drinking, you're not in a workplace situation anymore. One might argue that a boss should have his employee in his bedroom after a night of drinking in the first place, but IMO the responsibility on that issue is split 50-50.
Also I was under the impression that this girl was a volunteer who organized a charity event for him, not an actual "employee" per se.
