Since there is no New York state law two weeks notice requirement, employers do not have to guarantee employment to their workers. There is no specific law requiring notice to your employer if you choose to quit or leave your job.New York is an "at-will employment" state. Don't put in a two weeks. As soon as your onboarding is complete and you have a scheduled first day of training you quit without notice. It's fine to resign in person, but follow it up in writing. No. The law doesn't require two weeks notice. That's one of the benefits of at-will employment. A resignation letter should be written at least 30 days prior to the effective date of resignation. A two weeks' notice has generally been seen as a common courtesy.
