What is standard for a travel contract?

I signed my first contract, just that I would work for X amount, 40 hours a week. Specific shift that I would be working.

I know that I can request specific days off, like specific holidays.

But what else is standard for a contract? Or is that it?

Is there something that I do not know about??

I would ask other travelers, but frankly, when I ask them, I get a blank look.

Can anyone help?
