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.

day long, Sean's performance punishment is that he always has to stay late and take on
extra projects to make up for Steve.
