A couple of decades ago, our CEO decided to fire the IT guy and replace him with a dude with a much better attitude.
He discussed all pros and cons with other executives and HR - over the corporate Exchange server.
The administrator was not pleased as he read everyone’s email. Suddenly the CEO was signed up for websites with the company Amex, that I just don't think are legal, and certainly not moral. Lists of commonly used passwords in our company suddenly appeared on a Brazilian sever, and the main back up server was used to pirate movies. We even contracted with Cisco to get the guys out of the servers and they just kept coming back.
So Dave, I heartily second your advice. If ever replacing IT, discuss it at Del Friscos and be decisive.
Your examples are why you fire certain people quick and before they can hurt your company, your employees and you!
