The shittiest organizations and shit holes I've ever worked for were always union.
The best companies I worked for had no union. Why would you need the union if you do a good job.
It's scary that teachers are Union. They have no idea what they're teaching because when they were studying to be teachers none of the technology was alive. So now they have to deal with the YouTube generation and they're completely clueless what to do with that stuff. You might as well teach kids how to make video games, they are going to learn how to code and they are going to learn how to do art and collaborate in teams.
