For senior hires, where expertise, client trust, and leadership complexity are involved, the true cost, when productivity loss, management time, and team disruption are factored in, can reach multiples of annual salary. Yet most organisations never carry out that fuller calculation. They measure what is easy to measure and overlook the rest.

Ask a manager how their one-to-ones are going and they will almost always tell you: fine. The meetings happen, the topics get covered, the time passes. And yet the same issues surface a week later. The same person seems flat. The same friction stays unresolved. If the one-to-one is doing its job, why does so little actually change?
