When I was younger, I worked as an IT guy on a printing factory, we had 24 hours shifts. The day was a usual IT shit, and at nights we did a little bit of maintenance but mostly we were on standby to fix IT stuff in the factory, most of the printing was done on the nights so the fresh press goes out in the morning. Mostly we were paid handsomely to play WOW the whole night, and once in a blue moon go to the factory floor and reboot something or repair a patchcord or reinstall a memory stick or something.
Then the company got merged with the other media company, they took over the factory, and their first decision was to remove night shifts, because why do you need to pay those IT wankers, they don’t do anything most of the time. Of course most of us left but they had their own IT guys and everything was great, they were able to conserve so much money on salary, until one day one of the computers run out of disk space in the middle of the night and that clogged the whole damn factory, and since all the IT was home asleep, nobody was able to clear the cache, so nothing got printed, everyone involved lost millions, and the whole company was ultimately bankrupted because of this.
