In the U.S. the standard for most positions is 2 weeks, and for key positions 30 days. Most executives have it listed in their employment agreement, which is commonly 30 days. C level execs generally range from 30 to 90 days. The larger the organization the longer the notice period in general, I have seen a few extend up to 120 days but that isn't super common. It also isn't uncommon for a C level exec to give 120-180 days notice even if it isn't required. In the U.S. the vast majority of workers work in a right to work situation, which means you could quit & walk out today and there is nothing the employer can do about it. Likewise, an employer can fire you and only pay out what they owe you in salary and benefits and not provide any severance too. Of course some people work under unions too which changes everything, but that is not common with professional positions, and definitely not in technology. But even in those situations the notice periods are still pretty typically 2 weeks or 1 pay period, and generally do not exceed 30 days. But each union has negotiated agreements so that can vary of course.
