No I wasn’t, I’m not from the USA.

You are correct, it’s not even just one there are several apparently. AFT, UFT, NEA… Honestly I’m confused.

I’m glad the USA does have unions. But there seems to be some roadblocks when I read that some teachers are getting underpaid.

In developed countries teachers unionize. They have fair wages, ample benefits, lots of vacation. Their job is still very hard but they somehow feel more valued.
