One time someone said "Yes, I am surprised you fired me." I can't even tell you how destructive that was to my team. To be honest that person should never had been surprised nor my leadership team, but it happened and it caused havoc. It took years to fully repair the damage. I think he just really liked the job and didn't want to leave. Also the person ended up going to jail for unethical practices just 18 months later. I actually fired him due to being full of excuses or on the line of disaster and never asking for help.
