Positive tension with the Chair

The relationship between the Chair of the Board and the CEO is not meant to be that of a ‘comfy sofa’.  Positive tension should exist.  Push back should be expected, from both sides!  This positive tension enables robust discussion, challenge and the ability to shift positions.  Through this process good decisions can be made. If the CEO is in the Chair’s ‘pocket’, or vice versa, then why have the two positions?
