One-on-one coaching sessions provide the ideal forum to encourage employees to communicate with you, advance strategic vision, and attain goals.  Here you have a place catered to the needs of your individual employees, where you can focus on each of them in turn, working to improve their strengths and overcome their weaknesses.  Your sessions should be principled, but not generic.  Here you are a coach, not a manager.  Your aim is skill development through practice, not PR through pep talks.  These should be hard work, for you and for each employee.
