Communicating and celebrating the times when individuals have made values-based decisions is, of course, empowering and can provide role models. But perhaps more importantly, it removes the sense of futility that often prevents employees from speaking up.

Throughout history we have seen the tyranny of the powerful over the less powerful - think of the history of colonialism or of slavery - and the tragic mistakes made when important information was not "heard" or valued.

We are better able to bring the same sort of pragmatic planning and analytical pre-work to our values scripts that we would bring to any other business position that we espouse. This approach enables us to be more reasonable, more respectful, less impulsive and more constructive. Risk cannot be eliminated entirely but that is true in all of life.

I believed that we would all come to better decisions and we would create more humane and ultimately more livable and more sustainably productive workplaces if we knew how to speak to each other about difficult issues and if we were more able to listen to and learn from diverse points of view.

Time pressures are a reality of business life that cannot be eliminated entirely and that even can create a beneficial focus at times, it can be powerful to set aside discrete occasions where individuals are invited to step back, to look at their projects from different vantages, to consider input not usually examined, and so on. This again encourages folks to express alternative points of view.

I have to think that we all have - at one time or another - felt that our own voice was silenced or under-valued. Who among us did not have the experience as a child of feeling as if our parents just didn't listen?

By creating explicit occasions to invite dissenting viewpoints on a new project, strategy or policy, leaders enable employees to feel that their questions are welcomed and appreciated.
