For every (likely made up) story you have about how your father's uncle's brother's first cousin's roommate had a union job and it was full of lazy people
I had a student job with a community college while I went there only about a decade ago, while I uh, pivoted. And what I saw in the IT department was tragic. The primary system upon which the school depended was a HP-SUX quad Alpha, because that's what their software runs on. Then they replaced it with some ridiculously expensive many-way itanic box because that's what the vendor told them to do. On the old system, I got paid to implement ssh tunneling (with putty, naturally) to stop them from sending SSNs and other private student information across internet links in cleartext, because the sysadmin they were paying to do this stuff couldn't figure it out. Then I got paid to figure out how to implement ipsec on the new machine because the guy whose job that is couldn't manage that either. I was hoping to slide into that job but that guy bought a second Harley, and he had to stick around to pay for it. Or more to the point, so that the students and taxpayer could pay for it. He certainly didn't earn the money. My boss was quite competent, that was nice. My two coworkers were also competent, but lazy. I wound up doing job after job that they were supposed to do, because they didn't bother. One of them had severe short-timer's syndrome for the entire two-year span we were both there, with a countdown clock to retirement. He was a pro at stretching jobs out and making them take forever. He probably should have had a 75% pay cut.
Meanwhile, administrators have a different union from educators. This results in administrators and their favored assistants being paid dramatically more than the educators... you know, education? The point of the whole place?
I don't know if unions are as toxic in other industries as they are in education, but they're definitely a massive part of the problem with education today.
