Most of you have probably heard of the Peter Principle, a management concept developed by Dr. Laurence Peter. It observes that people in a hierarchy “rise to a level of incompetence.” They don’t start out as incompetent, but rather are promoted until they reach a level of respective incompetence. Besides a lack of training, there are numerous other factors resulting in incompetence in the workplace, such as sheer laziness, poor communication and lack of people skills. They show up late for work and often don’t look professional when they do. Communication ranks high among top people skills, but incompetent people also lack social skills like patience, politeness, sympathy and teamwork.
