James was disciplined for missing three deadlines in a row. His manager said that this was an unacceptable number of deadlines to miss. However, James knows that another employee has missed many more deadlines and not faced any disciplinary action. This case appears to violate one of the rules of in discipline.

Impartiality

Explanation:

For effective running of any business of corporate management, the top level bosses are required to be consistent in their decisions with all members of staff and being impartial in their discharge of punishments, promotions, bonuses, surcharges, etc.

James was disciplined for missing three deadlines in a row but another employee that subsequently missed more deadlines wasn't punished.

This inconsistency and partiality in judgement and discipline will likely affect morale at work and cause internal squabbles among staff which will lead to reduced output and a general sense of dissatisfaction.
