dnt like my job still young i worked thier for a year and what should i say when i put in my two weeks notcie what should be my reason for leavin?

Choose one of these letters from About.com to resign. I've read them all, and you should choose the one that best fits your situation. Don't be rude, sometimes it's good not to burn a previous job.

I'm about to use one of these letter myself ;-)

ALSO, you don't have to have a reason for leaving. If you want one, just say that you're grateful (or Thank you) for the opportunity, and that you want to endeavor (explore) in other areas.

Good luck!
