Indeed. The house holds most of the cards. But it's not risk-free per se. It's just a prisoners dilemma that hasn't had a chance to shift to the worst case scenario of "literally everyone leaves". Probably still a safe bet, but it's only as safe as the people they are gambling with.

Sad part is that it's bad but not necessarily "life or death" for many teachers as of now. But it may be that way if we keep going.
