if you are going to quit your job, you should give a 2 weeks notice.
Explanation:
There isn't a law that establishes that an employee should provide a notice of a certain number of days to quit the job. However, some companies have policies that establish that employees should give a 2 week notice and this is a common practice that is considered courtesy as it allows the employer to have the time to find someone to replace the employee and it helps to maintain a good relationship which can provide benefits in the future.
