Can you use vacation time for 2 weeks' notice? Managers may be able to deny PTO requests from employees who resign with a 2-week notice letter.It's 2 weeks notice, not 14 business days. 10 business days is 2 weeks. There's also the option to turn your "2 weeks notice" into a "3 weeks notice": state your intention to leave 2 weeks before your PTO starts. A common misconception is that two weeks' notice is a legal requirement. There is no federal or Arizona law that makes this a requirement. Customer: I gave my two week resignation notice. I leave in Arizona - a right to work state, so this was a courtesy and not a requirement. There are no federal or state laws that require an employee to provide two weeks' notice to his or her employer before quitting.
