Illegal demos a red flag?

You got it… If you don’t have a work permit that, is… And I understand you don’t need one…

I had a demo the other day, and got paid for it. I wonder if that is what happened to me.

Actually, I had another today. Same school. This time, they were more open about it. They called it “substituting”. I am beginning to think they just needed someone to cover a shift and ran an ad as they were legitimately looking for a teacher. At least I got paid.
