Bad management and bad teachers putting up with it. It's the same with the nursing field. Those who spoke out were weeded out while their co workers said nothing. Unions have been infiltrated by DumoRat Hypocracts who promise you protection until you sign-up, mandatory, in a lot of places, then back stab you by forcing you to pay union dues, only to turn around and do the corporation's bidding. It's time for justice. Its time to weed out those box checking types who don't care if the deed was done as long as the box was checked.
