> Although less explicitly, collective punishment is used in the office as well. For instance by letting an entire team work overtime if one of the team members screwed up his work and made the team miss a deadline.

A "good" idea (*sarc*) to either

- decrease the team cohesion (i.e. make the team members hate each other)

or

- increase the team cohesion in the face of a "common enemy" (the boss) who all of the team members will from now on hate

Both of these are likely not what a boss desires.
