Only history will judge the actions of Wikileaks and its founder Julian Assange to be positive or negative, as only history has judged figures such as Mahatma Gandhi and Nelson Mandela to be powerful forces for good.
Courage is an act, not a judgment. People who, because of a greater good, step outside of their comfort zone and face potential physical or psychological threats are courageous - their actions however (when judged by others) may not be so.
Building a courageous workforce is a powerful way to increase employee engagement, innovation and productivity, as well as increase the organisation's flexibility. But you want to make sure that your employees are all being courageous in the same direction.
Courage cannot exist without values. Courageous people take personal risks and put their self interest behind a belief that they are serving a greater good.
An organisation without shared values (and purpose, another form of value) cannot be courageous.
But a workplace with a strong sense of what it stands for and where it is going can become courageous.
And courageous organisations can change the world.
