You show up late to a meeting with a fellow product manager. Tardiness is the classic power move because it says, “My time is more valuable than yours, so it’s okay for you to wait for me.” To be sure, we’ve all been late due to circumstances out of our control, so it’s not always a reliable signal. But usually it says something. Think about it: Would you allow yourself to be late to a meeting with Barack Obama? Certainly not.
