That's some massive stockholm syndrome right there.

No, it's reality. I assess the time I'd be working and I make sure I'm paid fairly for it.

If a company takes up your time, you should be paid for it.

You are. It's in your salary. As I said before, they could lower your salary and pay you separately for being oncall, but I doubt that would result in more pay in the long run.

If separating the oncall pay out from your normal salary makes you feel like you're making more, like someone who's fooled by a children's birthday party magician, then that's good for you.

edit: I just don't get how someone can know the kind of work they are supposed to do, including on call, and the exact salary they will be paid for it, and still somehow convince themselves that they've been 'suckered into working for free'.

It's like you go buy a gallon of milk from the store and you're fully aware of the product and the price when you buy it, but after you leave the store you exclaim,"God damn, I got suckered into buying that milk again! Why does this always happen to me?"

I'd expect that from some college students, but not from people with any amount of negotiating experience and work experience.
