If 20% of your people cause 80% of the issues, what percentage of your admin time will be spent managing them?

In this scenario, the principle being referenced is often referred to as the Pareto Principle or the 80/20 rule, which suggests that a small number of causes (in this case, 20% of your people) are responsible for a large percentage of the effects (80% of the issues). When you find that one segment of your team is disproportionately responsible for the majority of problems, it follows that managing those individuals will take a significant amount of administrative time.

Given that this small group is a primary source of issues, the expectation is that a considerable portion of your time would be dedicated to addressing their needs, resolving conflicts, or managing the repercussions of their actions. Thus, when considering the possible range of administrative time that might go into managing these individuals, a range of 80 to 90% is reasonable.

This high percentage reflects not only the time spent on resolving issues but also activities related to supervision, guidance, and possibly even corrective measures tailored to this problematic group. When one segment of the workforce is so influential in generating issues, it is logical to dedicate a substantial amount of your administrative efforts toward them to improve overall productivity and morale. This makes the choice of 80 to 90% the most consistent with the dynamics described
