Boss accuses employee of not working their hours, employee turns the tables and provides proof to HR that the boss is the one not working their hours: 'Do we need to get HR involved or are you going to calm down?'

It's often said that we accuse others of the thing we're most guilty of, our own guilt subconsciously directing our thoughts in that direction. For instance, your boss who is constantly hounding you about your hours and accusing you of having not worked them is probably not working their full hours themself, either slacking off at their desk or making excuses for leaving early that they wouldn't accept from anyone else, amounting to hours of time over the course of a month. 

This, of course, takes forms in many different shapes in our social and political interactions, even our parents trying to prevent us from sneaking out at night (despite the fact that we never cared to do so) is really just because that's something they would have done at our age.

This boss consistently made an issue of their employee being "tardy" which eventually escalated into a confrontation that needed to involve HR. The employee had done their homework, however, and was not only able to prove that they had actually worked more than their required hours but that their boss had not been. Which, of course, their boss was even less thrilled about.
