Long ago, before Dotcom went Dotbomb, I worked for a firm where the CIO was being paid kickbacks by our hardware reseller. He was terminated for other reasons and, shortly after he left, our head of network ops got a call from the distributor asking where they should send the bonus check that was due to him. They clearly thought that with the CIO gone, the head of network ops would be down the with the deal.
Unfortunately for them, and fortunately for him, he was absolutely not down with the deal and reported the whole thing up the chain.
We were overpaying for hardware and the previous CIO had been splitting the difference with the distributor.
If it's unclear to anyone on this thread why that is both illegal and immoral... perhaps you are in the wrong business?
