That's generally how it goes. We could spend hours talking about what happens in those situations.
When my niece was in her first year of uni, I asked what her plans were. Teaching! As the time passed, she changed her mind. She got her BA (Hons) and started working on her masters. At the same time she was exposed to the primary school stream, working as a volunteer. One day, she asked me what it was like to teach and not just help out. She had become jaded.
"They haven't ever left school! They've never had a real job!"
Yes.
"And the unions control everything they do. There are several levels, like the Catholic board. Protestant. High school federation."
I know. And there are more than that. Welcome to the world of academia. If you stick around, it will only get worse, unless you can find a placid inner place to hide when they start talking.
Now she's looking for a public sector job. Still union, but better than the teachers, IMO.
