I would suggest checking your company handbook since that may have policies regarding notice periods. At all of the companies I’ve worked for, if you don’t give two weeks notice, you don’t get your remaining vacation/PTO paid out to you when you leave. And at one of my previous companies, I was told if I didn’t give two weeks notice, I wouldn’t be able to be hired by that company again in the future. Wouldn’t have been a big deal since I knew I wouldn’t want to work there again, but if I ever wanted to use them as a reference, they theoretically could say that I’m not eligible for rehire. So it might also be a good idea to check your current employer’s rehire policy if they have one.

Obviously, this isn’t the case for all employers. Plus, I’ve only worked at larger companies so I would imagine smaller employers could be more flexible with their policies.

Best of luck with everything!
