How about what you shouldn't do when quitting a job?
I've seen resignations handled in a variety of ways - both good and bad. One employee left a note on her manager's desk saying she quit and wouldn't be back.
Another employee got mad, yelled at the boss, and walked out the door. Still another sent an email saying he wasn't coming back. Not the best way to resign, of course, if you can help it.
The employee who resigns gracefully, gives two weeks notice, writes a polite resignation letter, and thanks the employer for the opportunities they had during their tenure at the company will leave on a positive, rather than a negative, note and that makes good sense.
These resignation do's and don'ts will help you resign with class rather than causing trouble on the way out the door.
It's also, by the way, important to write a professional resignation letter to formalize your departure. Review these resignation letter writing tips to make sure you're including the right information in your letter - and you're excluding the information that you don't need to share with your soon to be former employer.
