I have a neighbor who left to go to FedEx. (I am a DAL FO). He said the second he gave notice they removed him from the schedule. They paid him to the date he said he would be there in his resignation letter (through his sick bank if memory serves me). He gave about 3+ weeks notice.

He was surprised how they handled it to be honest. PM if you have any other questions or a summer week of vacation you need to offload.
