I spent years leading people who do physical work — sales floors, warehouses, service routes. I hired them, trained them, and lost more of them than I want to admit.

Years later, I found the research that explains what the work already taught me. That's what I write about: hiring that predicts something, onboarding that survives the first week, feedback that lands, and why good people actually stay — in plain language, with the receipts from both sides.
