We recently had a driver come in and quit. No notice. Been with the company for 7 years. I and several other drivers(even the CS) tried to talk him out of it when we heard what he planned to do. He was adamant and even went as far as to sign his letter of resignation. In an unprecedented move, management (CS AND center manager) held the letter of resignation for 2 days giving the driver a grace period to come to his senses and reconsider his choice. Which he did. Life is about choices and consequences. As a work group we cannot allow this driver to come back like nothing happened. What should be his consequence for being allowed to keep his job?
