I once had a sales rep contract terminated, and I’d seen it coming a mile away. While I didn’t know exactly when it would happen, I’d been thinking long and hard about it and knew exactly what I was going to do.
I took a 5PM phone call from my manager and got fired. Then I made one phone call. The next morning I told everyone that company X had terminated my contract and I was going to work for company Y.
It would’ve been customary for me to simply say I was leaving company X to go to work for company Y. But I refused to do that, because I was really popular with my clients and I didn’t want to make anything easy for my successor.
