I recently accepted a job starting in a month. I no longer wish to accept this position as taking it would mean moving to a new city, which I knew when I applied, and I now can not make the move. I need to write an email to quit the position I've accepted. What sort of things should my letter say or even a pointer to a appropriate form letter would be appreciated.
The job is in Canada for a government. I can't call because I have no phone service during business hours for the next two weeks and I'd probably melt down anyways even if I did.
