In a lot of places in the US, notice is never legally required. You’re allowed to leave at any time, regardless of position. Would it screw over the company? Yes. Is it unprofessional? Yes. But you have zero obligation to give notice.

I work a high-paying job in tech with plenty of responsibility, but due to how upper management completely screws me, I will likely be leaving with same-day notice. If the company wants respect, they must first give respect.
