Then it sounds like they need to be educated on what rights they have to protect themselves in their schools. What the heck is the Teachers Union doing?
Nothing. MCPS Teachers don't realize that MCEA is what is known as a "Yellow Union"; it often just does Admin's bidding. When MCPS clearly violates the contracts, the Union response has often LITERALLY been, "we asked MCPS if it was a violation, and THEY said NO. So what can we do?"
Every school I've been at, things are so cordial that Admin is actually often present during Union Votes. A real union would not allow that.
I'd actually support a strong union, but the current lap-dog union makes me happy about Janus v. AFSCME.
