Re: IT? Not so much.
Here's a little story : in a bank in Luxembourg, a peon was brought in from a staffing company to oversee secure transmission of financial data in PDF format. His job was basically to drag PDFs from on folder to a different folder in a different folder in a different environment. Fascinating job, I know, but hey, apparently they pay (peanuts) for it.
Of course, he was surrounded by high-level personnel and management who were, as I was told, telling him to go faster and faster as the minutes went by. What had to happen happened, and the poor guy mis-clicked and opened a PDF instead of dragging it over. He closed the file immediately, but that did not prevent him from being fired on the spot.
So sorry, but you can get fired in IT just as fast as anywhere else, if you're in the wrong place at the wrong time.
