No. Off the top of my head, my understanding is that the vast majority of full time jobs in the US are at-will employment which means there is no required notice period. It’s considered a best practice to give two weeks or more but that’s a social contract and not enforceable in any way. In the past, when employee reference checks were a real thing, that two weeks might buy you a better reference, but even that has been stripped away now with references handled by HR and only confirming dates of employment and conditions of termination (this is to avoid lawsuits I think).
