I've been on three travel assignments and luckily they were great. The staff was so short they welcomed travellers. The perm staff and travel staff are separate enities as far as $ but travelers have to abide by the rules and regs of the host hospital. I've never encountered different expectations for travelers vs perm unless it was written in the contract (ie call, shift rotation, etc). Didn't you get an orientation to your new unit? As far as $, if you're not making more than perm staff then something is amiss (as far as I'm concerned). Maybe it's your agency? Don't give up travel because of one bad gig. Good luck!
