The time an employee starts or finishes work has nothing to do with performance. I learned this the hard way. As a young engineer I thought productivity meant one thing: be at my desk, complete every task, never stop. First in, last out. I wore the long hours like a badge. I was busy. I was exhausted. And I was overlooked. Then I watched colleagues who left at 4 get promoted ahead of me. They weren't working more hours. They were working on different things. They planned around the project, not just the task list. They negotiated for resources before they ran out. They sold their ideas to managers and customers. That's when it clicked. Hours measure attendance. They don't measure value. I stopped optimizing for time at my desk and started optimizing for impact. I got promoted. I earned more. And I finally delivered projects everyone else called impossible. Performance was never about the clock. What's one thing you do that drives real results? But never shows up in your hours?
