Within the State of California, employment may be terminated at the will of either party. California laws say that, in general, you are not required to give your employers two weeks notice – or any notice – prior to quitting or leaving a job.You don't have to worry about giving two weeks' notice to your employer. There is no requirement that you must give your employer two weeks' notice. If an employee quits without giving at least 72 hours' notice, the employer has 72 hours to pay them from the time of quitting. California's labor laws do require you to give at least 72 hours' notice if you want your final paycheck at the time you leave. In California, is it legal to add a paragraph stating they must give 2 weeks notices in an at-will employment contract? A: The at-will employment law of California allows an employer to fire an employee with or without cause and with or without notice for any lawful reason. This means if your contract states a 30day notice period, you are obliged to provide such notice to avoid potential breach of contract issues. This is because California is an atwill employment state.
