When you’re a leader — no matter how long you’ve been in your role or how hard the journey was to get there — you are merely overhead unless you’re bringing out the best in your employees. Unfortunately, many leaders lose sight of this.

Power, as my colleague Ena Inesi has studied, can cause leaders to become overly obsessed with outcomes and control, and, therefore, treat their employees as means to an end. As I’ve discovered in my own research, this ramps up people’s fear — fear of not hitting targets, fear of losing bonuses, fear of failing — and as a consequence people stop feeling positive emotions and their drive to experiment and learn is stifled.

Take for example a UK food delivery service that I’ve studied. The engagement of its drivers, who deliver milk and bread to millions of customers each day, was dipping while management was becoming increasingly metric-driven in an effort to reduce costs and improve delivery times. Each week, managers held weekly performance debriefs with drivers and went through a list of problems, complaints, and errors with a clipboard and pen. This was not inspiring on any level, to either party. And, eventually, the drivers, many of whom had worked for the company for decades, became resentful.

This type of top-down leadership is outdated, and, more importantly, counterproductive. By focusing too much on control and end goals, and not enough on their people, leaders are making it more difficult to achieve their own desired outcomes.

The key, then, is to help people feel purposeful, motivated, and energized so they can bring their best selves to work.

There are a number of ways to do this, as I outline in my new book Alive at Work. But one of the best ways is to adopt the humble mind-set of a servant leader. Servant leaders view their key role as serving employees as they explore and grow, providing tangible and emotional support as they do so.
