Much of it comes down to a difference in perception about styles and priorities of management. Young managers should begin by spending time getting to know these older colleagues. While some may view this as unnecessary socialization, not doing so can be the critical disconnect between older workers and a younger supervisor. Even dedicating an hour of time toward each individual will demonstrate that the manager appreciates his or her experience and value.
But this is not where the effort should end. Continue by keeping these people in the loop. Ask them what they think. Solicit their insights on all manner of issues. Chances are, these workforce veterans possess some native knowledge about certain situations that could be very useful. Successful leaders know that seeking the ideas of subordinates enhances, not detracts, from their power and influence. If these individuals take a liking to the supervisor, they will share both the insights that might be obvious but also the nuances of navigating the politics.
