OT Tex re teacher regulation
"Unions are tasked with representing the interests of members. It would be a conflict of interest to require unions also to advocate against members...
Manadatory bar associations and medical societies, on the other hand, are both enforcement and professional advocates; and one cannot serve zealously two conflicting masters."
(Precisely my point, spelled out well.)
Do you know if US teachers (secondary or college) are represented by unions, typically or at all? (Things may be lefter here in the frozen north.)
