I'm reminded of an interview I heard of a holocaust survivor. The women worked hard to capture their cultural recipes, and there are a few books similar. When asked how people could let the Holocaust occur, she replied on the interview "…one small step at a time." The Road to Abilene is a story told by Pat Murray, leadership guru. Basically, it's the tale of a group of people all getting in the car to go someplace no one wants to go but all are afraid to say that. Each, through their silence, agrees to go where they don't want to go. Pat says "You stand for what you tolerate. Every choice made is a speech to others."
When working with teams, Pat speaks of the words and actions seen vs. the inside moves that are not seen. Think of a time when you were part of team, and the words and actions in a meeting were neutralized by behaviors later in other places. How does your team see you? Teams need to know not only their individual purpose and values (non-negotiables), but need to implicitly establish the purpose and values of the team as a whole to feel fully vested.
Meetings are another complication that Pat Murray speaks of. I love his quote "We all attend the same different meeting." In my CEO group, we often talk about 'the meeting after the meeting.' The lack of authenticity in formal meetings, trumped by gossip by the water cooler is a cancer to a team. "There is no trivial act." Leaders must, as Pat says, "…act from the future. You stand for what you tolerate." This is true for every member on the team, not just the leader. Each member must be equally accountable. Watch every little move and behavior in yourself and others to ensure you are aligned to the future you are all vested in.
