Thank you for trusting your question to JA today. I am a licensed attorney with over a decade of law practice and over 20 years of experience in the legal field. I’m happy to be of assistance.
Two weeks notice is not a mandated legal requirement under any law, unless an employer has a specific contract with an employee requiring it. It is, instead, a courtesy created between employers and employees. Law says very little about it, but we have to deal with its implications from time to time.
For example, when you give notice you are actually legally resigning at that very moment and then you are offering the employer the right to two weeks additional work, if they want it. Many employers do, but some employers don't. The employee isn't entitled to work through their notice, and they aren't entitled to pay for those two weeks if they don't work. The employer's decision to not accept the two weeks of work doesn't convert the resignation to a termination.
Now, for purposes of future employment, if he offered a two weeks notice and the employer didn't want that time frame, that employer can't later say "he failed to give notice." I mean, they can, but they can't do it legally. If they did, they would be subject to a defamation of character lawsuit from your son for any lost jobs that their false statement caused. He should certainly get something in writing, if he can, indicating that they were offered two weeks notice but didn't accept it. Then he'd be completely fine. Even without it, he can simply write out his resignation, state that he intended it to be on a certain date, but his boss did not want or need the notice period worked, and so his new final date is (whatever that date is). Then he can sign it, date it and turn it into HR.
