I knew a guy who had a low level data/reporting job. He had several daily/weekly work responsibilities, including a bunch of reports that needed quite a bit of tweaking from raw data to finished product. But like I said, low level.
We didn’t find out until way later, but he had set up macros for each of his major responsibilities where he could. Once set up, he’d just run the macros to do his work, but then he’d (smartly) hold off on delivering the reports until just a little before the deadlines.
He’d hit every assignment and was seen as reliable. He also would complain about the workload so people would leave him with that work. I doubt he did a full hour of work a day after he set up what he did.
Eventually he left the job for one with better pay. But damn did he work lazy. Also, he was smart not to reveal until the end, because had he told them about it he would have gotten a pat on the back and would have been given a whole other workload, on top of maintaining those macros/etc. Dude milked the job, not the other way around.
