If you're straight and the other person is the same sex and also straight, you're OK being alone together. If you're gay and with a person of the opposite sex, you're OK being alone together. Anything else is risky.

Seems like a lot of guess work. I fear I'd be doing something wrong just by trying to figure out whether or not the other person was gay.

So a straight guy can say to another straight guy "Hey man you have a nice ass?" without legal repercussions?

One more reason to try to work from home I guess.

Anecdotally, I've found myself in situations which would easily qualify as sexual harassment more than once. Each situation would have been "OK" by your definitions, on the surface.

Trying to judge risk in terms of gender or apparent orientation seems a bit silly to me.

Isn't this being a bit too absurd?
