I think of teachers as public sector because most are paid by taxes that are taken from people and their unions fund parties like the NDP that will scratch their backs. The public sector is the sector of the economy least responsive to price signals (choice) and even the tiniest hint of a hairline crack in that sector is a sign of hope to me.
"Most notable, however, is the impact these younger teachers are having on teachers unions. The unions usually negotiate rules that favor seniority, so younger teachers are generally the first to be let got when cutbacks are made. Unsurprisingly, those teachers are pushing for unions to adopt measures they have traditionally opposed, like merit pay, or are breaking with unions entirely, as the WSJ reports."
