Every manager is in the coal industry.
More than likely, you have plenty of coal on board. They fuel the fire that drives your economic engine and delivers high-quality care to those you serve. Your task is to locate those who can become diamonds, top performers every employer in your market craves, with just the right amount of pressure and patience.
Scan your staff for those with diamond potential. Invest in him/her by assigning greater responsibilities, expanding her skill set, and sending her to seminars, workshops, management training programs, and advanced certification training. Expect her to be reluctant at first. She's still a lump of coal for a reason, and it's likely she hasn't been pressured.
If she resists, back off. Some pieces of coal takes a while to share your perception that they have diamond potential. A diamond in the rough will eventually come back to you asking for more pressure. But if coal wants to stay as coal, you should let her. She fuels your engine, remember. Apply pressure when it's not embraced and she'll leave to fuel someone else's engine. In the meanwhile, find another piece of coal that might become a high-value asset and invest there. They're everywhere. Finding them gets easier the more you look.
The ultimate goal of every empowered manager is to take the lumps of coal on your staff and make them diamonds so valuable you can no longer afford them. You're in the coal industry, for sure, but you also deal in precious gems. You turn coal into assets of such value other employers or industries trip over themselves with offers far beyond what you can counter-offer to keep them.
Mere managers who increase the market value of their staff feel distressed and betrayed when the diamonds they "created" jump ship. Empowered managers are ecstatic. They've added value to a person; increased their market value. The mere manager invests in his staff to serve himself; the empowered manager invests to serve his subordinates.
Here's the irony. Whether they're invested in or not, those who work for mere managers are going to either remain lumps of coal, or jump ship anyway. Because of their nature, self-serving employers don't inspire loyalty for many reasons. Self-investing is only one of them. However, those whose value is enhanced by servant-managers rarely want to work for someone else, even for a premium.
With enough pressure, a lump of coal becomes a grateful diamond. There's someone on your staff who needs pressure.
