Due to a high level of motivation and repeat successes you are selected by your superiors to do more
work than your peers because you do your
job and good at it. This frequently entails extra hours, multitasking, et cetera. The punishment is that you get to watch the underperformer, who is not doing their job, get rewarded via time off, free time, leave work on time and so on. This is common in the military, other
government jobs, or large corporations where, due to bureaucracy, it is difficult to get rid of a bad employee.

Steve does
nothing all day long, Sean's performance punishment is that he always has to stay late and take on extra projects to make up for
Steve.
