Definition: Giving two weeks notice is the standard practice when resigning from a job. If you have an employment contract or union agreement that states how much notice you should give, abide by it. If not, two weeks notice is appropriate, but not required.
If your employer asks you stay longer than two weeks (or the time period in your contract) you have no obligation to stay.
Also, your employer does not have to accept two weeks notice (unless it's in your contract). They can end your employment immediately.
