Giving a 2-week notice is fine. But that doesn't mean you need to start the next job in 2 weeks.What's your proof of the day and date you resigned? It's fine to resign in person, but follow it up in writing. Just write a quick note. A two weeks' notice has generally been seen as a common courtesy.

I highly recommend talking to the manager in person. Learn how to write a professional two weeks notice letter with our easytouse template.
