Managing People

Manager quality is reported to multiply turnover risk by four (vendor research), and SHRM puts replacement at 50–200% of annual salary (professional body) — which converts the argument into a line item. For a related reference, see further details.

Poor management means four observable things: no clarity about what good looks like, no visible route from effort to consequence, no safety in raising problems, and no attention to trajectory. None is about personality.

Psychological safety means being able to raise a problem, admit a mistake or disagree without expecting a penalty — not comfort, not niceness. Survey research puts only one in three US employees strongly agreeing they can speak up without fear.

The one-to-one carries the two largest retention factors and is the meeting most likely to be cancelled. The cancellation rate is itself the signal.

The annual review does four incompatible jobs at once, and nobody discusses a weakness candidly in the meeting that sets their salary.

Managing people you cannot see changes what information arrives, not whether the work does — output holds and trust does not.

And a resignation is an announcement, not a decision: the decision was made months earlier, during a period with no signals in any system.

• About to Leave

  The decision is usually made months before the resignation. Six signals, and what is still available at each stage.

• The Four-Times Factor

  Manager quality moves turnover risk more than pay, workload or flexibility. What the numbers say and what they do not.

• One-to-Ones

  The meeting most likely to be cancelled is the one that carries the two largest retention factors. How to make it worth keeping.

• Performance Reviews

  The annual review does four incompatible jobs at once, and separating them is most of what fixing it actually means.

• Psychological Safety

  Not comfort, not niceness. The specific thing it means, why it predicts performance, and four observable signs it is absent.

• Managing People You Cannot See

  The evidence says output holds and trust does not. What actually changes when a team is distributed, and what does not.

• What Replacing Costs

  Half to twice annual salary, and the visible third is the smallest. Seven components, and the arithmetic to run on your own numbers.
