Carelessness costs cash
I had a manager who was let go due to a personality clash with a more senior manager (the better manager left, of course). And what also went? A smartphone, a tablet and a laptop. My manager had them in his possession, realised this, and tried to return after he had left the company (he had been ill when the remainder date actually happened), but could not get anyone to take them off his hands. He used the phone for over a year, free, by way of pay-back. The laptop and tablet are sitting somewhere, locked down and unusable, unless they fall into evil hands. Not a f*ck was taken by the bank about this equipment.
