Jack Welch’s book, Winning, was hailed as the best management book ever. It is still thought provoking, even if his own legacy has been questioned.
One thing he says about leadership is that it is defined by coaching. Every interaction should  coach and build self confidence. Coaching is critiquing and guiding. Self confidence is built by pouring out encouragement, caring and recognition. So employees have to have opportunity to fail and not get canned for it. Indeed, he blew up a warehouse!  Wow! How different from my observations, where  doing what was agreed upon was negatively rewarded!
He says it is a rare boss who can get results without being a people person. He says we don’t celebrate enough — and not with company parties but with ticked for the families to Disney land!
Of course, none of this can happen without factual evaluation, without candor, and without a culture of differentiation.  With this, though, real trust and great results can be built.
Coaching that builds confidence. Thought provoking.
