Overreaction only startles and stresses the people in your charge. Is it worth it?
Perhaps the point of an overreaction is to motivate action. But are those actions out of motivation to achieve or out of fear of reprisal?
A leader might operate with this golden rule: everything bad that can happen will happen.
Because of that, the best thing a leader can do is prepare the team for disaster response. Drill relentlessly. Fortify the team’s mind not to react negatively to another person’s overreaction. But instead, have a clear-minded set of protocols for what to do next.
