I know some good teachers and I know some bad ones, really bad ones. Unions make it so the bad ones stay on while sacrificing good teachers for the dues and donk campaign donations (but I repeat myself). Until the good ones speak out it will continue and they are complicit.
A union has never helped a company become more efficient or it's bottom line. Same goes for the teachers unions. Not only do they not help our children, they actively use our children as props to the detriment of our children. Many of the teachers look at the job of educating our children as a game they score by how much they can get out of the system for the least amount of work. Much like the social safety net leeches.
