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.
