Good point; the wealthier the educators got (many can now take skiing vacations during "winter breaks"), the more cowardly. And when they do stand up, they stand alone.
Back when I was first hired, I went to a union meeting. During the questioning period, a black teacher went to the mic.
He demanded two things from the union: That we support a quota system for hiring more black teachers, and that we file a protest over the number of black students being suspended.
Our union president was a tough old Italian who was a former steelworker before becoming a teacher. No to the first demand he said. We want to see the best people hired, period.
And no to the second demand. If any kid misbehaves, black or white, he should be suspended, period.
You would never hear those answers from today's union leaders.
