D13. Everyone quits a job at some point in their lives. You never know when you'll need a reference or have a connection cross your path. It's important to leave EVERY job on a positive note, no matter how bad it is or how much you hate the manager. Two weeks notice is the standard. Do Your best to give those two weeks as your reputation as an employee follows you throughout your career! It's true!! You are leaving a job and moving on. Write an official letter of resignation to your manager.
