Of key importance is making employees feel safe giving notice - that they will be treated well and won't be pushed out prematurely. The more notice an employer has of an employee quitting, the smoother the transition will typically be. If employees feel safe giving notice, they will not feel like they have to wait until the standard 2 weeks to give notice. One step further - really good companies (and managers) will make employees feel comfortable being open about being READY to leave (i.e. they are looking for a job or to go back to school or whatever). That gives the company even MORE time to plan. If an employee feels like they can say this before they have a job in hand, then they are more likely to be open about it.
