Communication must flow in both directions if it is to flow at all. Information won't surge up where it barely trickles down. Support means showing concern for subordinates as people. It means being available and approachable. It means helping people, coaching them, encouraging their ideas, and definding their positions.
Respect feeds on itself.
The most important form of respect is delegation, and the second most important is listening to subordinates and acting on their opinions. Here, the law of reciprocity tends to rule. When supervisors use a lost of fine words about trust and respect but behave disdainfully, subordinates are likely to respond in kind. Fairness means giving credit where it's due, being objective and impartial in performance appraisals, giving priase liberally. Chronic lack of fairness will dry up trust and candor quikcly, but every act of support and fair play will prime the pump.
