Who has the power to force teachers back to work at their old salary? Chicago mayor? Illinois governor? USA president?
For how long can this be forced? E.G., is a 5-year effective suspension of the union possible with one person's executive order? Of course, teachers could still quit on their own at any time, so my question pertains just to the union's action.
I know laws could be rewritten at any time to allow anything, but let's assume that no law changes are ever made.
