What is "a long time" anyway?

I absolutely love the lead for this article:

There wasn't a single incident. His frustration had been building for a long time.

In early November, Gibbs High School world history teacher Neil Cammardella realized he had to get out. Well liked by students and teachers, the 26-year-old quit his first real teaching job after just two years.

So which is it? "a long time" or "just two years"?

*sigh*

Stories (and teachers) like these are IMO a significant reason that people see teachers as incompetent martyrs. We suffer through a rotten situation because we're not capable of doing anything better.

In fairness, I don't know anything about the situation beyond what's reported in the Times, but that article sure makes Cammardella look like an idiot.

(And part of it is my bone-deep conviction that honor is Terribly Important: you don't break a contract in the middle of the year. I can understand, if not excuse, breaking contract your first year because you honest-to-God didn't know what you were getting into, but "after just two years" means he was - what - in the middle of his third year?)

My parents were always involved in my education... I thought that's how all students were. I didn't know such a large majority of students had so little parental involvement.

I think he lived under a rock. I feel like Hermione: "Don't you READ?!" I hope like anything we didn't graduate from the same university.

And the administrator who hired him ought to get a serious pay cut.
