Quote from Billy5949
what if I hate this traveling? What if i cancel my assignment for no other reason except that I want to go home? (Not that I want to, I just want to know.)
If you hate traveling when you get to your assignment, you simply remind yourself that it IS only temporary - 13 weeks, and you can go home when it's done. If you are really worried about this, look for your first assignment within about 100 - 150 miles from your home, so that if you get homesick, you can easily go home for a few days when you have 3-4 off in a row.
If you cancel an assignment "for no other reason except that I want to go home", you are breaking your side of a professional agreement. When you signed, you said "I will fill this position for X number of weeks". Your company will be well within it's rights and the terms of your contract (read it carefully) to charge you for all the costs incurred for apartment,furniture rentals, utilities and possibly any penalties paid to the hospital for a broken contract for the remaining period of the contract. You will also have blown your reputation with that company and probably not want to use them as a reference.
Don't mean to sound harsh, but this is reality and it's better to understand what you are agreeing to beforehand. Traveling can be a great lifestyle, but it's not for everyone - only you can know how you react to new places and situations.
