There are people who find jobs that require very little work, and its probably easier to find these jobs in offices. It works very well with technical work that management do not understand, and where output is difficult measure. its possible that people on HN might know of some jobs that fit this…

There are extreme cases, such as people dying and no one realising that their work is not being done, and that is rare, but a certain amount of slacking off, spending time of social media, etc. is not at all uncommon.
