High turnover in one department is encouraged or tolerated so that institutional memory never builds up, resistance never organizes, and each new hire accepts the changed state as normal.
An example
Veterans on a wireless carrier's business retention team said the new commission plan would push them to sell plans customers did not need. The vice president who owned the team did not argue with them. Over the next three years, quotas were set so that most reviews landed in the bottom two bands whatever the effort, senior openings went to outside hires, and workload grew faster than headcount. Turnover ran near sixty percent a year against a company average of eighteen. By the third year, median tenure on the team was eleven months. Nobody on it remembered the old plan, and the last two veterans were described in a staff meeting as not adapting. Exit conversations were held and never written up. The board saw only a company-wide attrition figure.
Why it works
Each new hire accepts the changed state at almost no cost: no loyalty to the old role, no peers mourning it. Resistance looks worse as memory leaves, because its legitimacy came from many voices who remembered. Holding out gets costlier for the remaining veterans, who become conspicuous and easy to label as not adapting. Policies push the same way: heavy workloads, reviews tilted low, outside hires for senior roles. Voluntary turnover is the alibi, so it also needs a labor market that supplies replacements and tolerance for lost productivity. Its visibility lags by one replacement cycle, which is its protection.
The thinking behind it
Thomas C. Schelling Schelling's Micromotives and Macrobehavior (1978) shows how a population can tip quickly to a new state once a threshold is crossed. As newcomers replace veterans, a department passes a point where the changed state is simply normal and the remaining holdouts look out of step. Tracking median tenure by department shows the approach to that point before it arrives.
Mancur Olson Olson's The Logic of Collective Action: Public Goods and the Theory of Groups (1965) shows that a group organizes only when someone bears the cost of organizing. Constant turnover keeps any group in place too briefly to pay that cost, so resistance never forms. Moving memory into documents, alumni networks, and customer relationships keeps the shared asset alive when the group cannot.
Warning signs
One department's voluntary attrition runs at multiples of the company rate for consecutive years while its median tenure drops every cycle. Most reviews there land in the lower bands regardless of effort. Senior openings go to outsiders. The few remaining long-tenured staff are described as not adapting. Exit conversations happen but leave no written record.
How to defend yourself
Get the memory out of people's heads before they leave, because once the people who remember are gone, the argument cannot be won.
- Write things down: decisions, the reasons for them, commitments made to customers, the old terms and why they existed.
- Keep written records of exit conversations, and ask that they be preserved.
- Build alumni networks and customer relationships that outlast any one person's tenure.
- Ask human resources, legal, or a peer leader to compare the department's review distributions and workload with other departments.
The evidence sits in policy choices, review distributions, workload calibration, and promotion timing, more than in headcount.
How a leader shuts it down
Report turnover and median tenure by department to the board as their own lines, and ask why one keeps resetting. Preserve exit records in writing. A function churned this way also fails at its real job, and the failure surfaces as a missed compliance event or a safety incident, so treat persistent churn as a risk signal.
