What is the law for NJ when an employee gives their 2 week notice?? In this case...if the employee is advised they are not needed for the entire 2 weeks and is dismissed, is the employer legally responsible for paying the employee for those 2 weeks regardless??

Thanks!

No. Nothing in Federal law and nothing in the law of any state makes an employer liable for paying the balance of an unworked notice period, no matter what the circumstances or whose decision it was for the employee to leave before the notice was up. The only possible exception would be if the employee was working under a binding contract which guaranteed such pay.

For the record, many employers will pay out such time voluntarily. But they are not required to do so by any law.
