Tony Barzar, a 60‑year‑old cashier at Costco in Tucson, Arizona, earns $33 an hour after four decades of service. He begins each shift at 9:02 a.m., guiding shoppers through six self‑checkout registers while maintaining a brisk pace.

Costco’s strategy rewards longevity. Executives view seasoned workers as *secret weapons*, noting their reliability, speed, and ability to mentor new hires. The company’s culture encourages retention, reducing training costs and preserving service standards.

For investors, Costco’s focus on high wages and long‑term employment signals a commitment to employee stability, which can translate into consistent sales volume and lower turnover expenses. Retail competitors may feel pressure to match or exceed Costco’s wage structure to keep talent.

The model demonstrates that elevating hourly pay can yield a loyal workforce, boosting operational efficiency and customer satisfaction—factors that directly influence profit margins and share performance.
