When a leader decides to repent (I know that term conjures images of a fire and brimstone preacher, but it simply means "to turn around") it's a great thing. It signifies an awakening and a desire to change. I applaud leaders in, and out, of the corporate world who are courageous enough to make this type of move.
Now for the painful dangerous part.
As much as I would love to tell you that all of the followers will applaud when a leader turns around, I can't. There will be opposition and resistance to the leaders new-found awakening. The why question is multi-layered, but one big answer can be found in the history of the leaders direction and actions. For example, if the leader has for years only praised you when senior management was around, then it's a sign of career posing. It takes time (a lot of it) for people to accept and believe in the change from counter-genuine to authentic.
The dangerous part is found in the leader who gives into the temptation of giving up because of skepticism on the part of their followers. Our culture likes results fast. But the leader should not expect speed here. If the leader can set the expectations appropriately, then the chance of perseverance grows markedly. The take-away here is, don't give up if you believe in the "turn around."
Make the decision to turn around…you won't regret it.
