Culture of Complaint

The Fixed Operations Manager & I (GM) recently went to a breakfast seminar on Cultural Change. One point highlighted was the culture of complaint - that negativity, blame and justification can become a way of life. What do you when the DP complains? Can you ignore the leader's setting and operate positively, keeping staff motivated, keen & happy?
