My dad's good friend just went through this, only for retirement, not another job. He gave his two week notice since he was planning on retiring in the summer anyways. There are only 6 guys in his position (very high up) and currently 2 are unfilled and 1 was also retiring soon. He knew this and was prepared to stay if they wanted him bad enough.
At first they were pissed because usually such a high up position gives more than 2 weeks notice and his response was he gave them 1 week, 6 days, 7 hours more notice than they would have given him if they fired him. It worked out and he is staying until the end of the year and getting a nice chunk of change to do so.

Companies want loyalty just like workers would like certainty they wont get fired...neither usually happens.
