I see so many people check out their last two weeks (or months!) on the job. Â I have a personal policy against it. Why?
1.) Empathy
You wouldn’t want someone checking out on you.  If you are somewhere, be there. Help smooth transitions, document tribal knowledge, and set those you leave behind up for success as much as possible.
2.) Reputation
You’ve established a reputation for years.  Don’t blow it away in your last month. Once I’ve left a company, I want to be remembered fondly as a person of great work and high integrity.
