I have worked for many managers who love to hit the panic button. Our life in retail is like that. Things are going normally, and then the market manager (boooo) comes into the store to tour (retail lingo for walk around and find all the problems). They get upset and then our manager runs right over to the panic button and gives it a push. Then hell breaks loose. It was bad enough, but pushing the panic button doesn't fix anything. It makes it worse.
Now the associates are freaking out and worried. The stress level is high. People are snapping at one another, so now the problem is magnified.
You must always be the picture of control. That doesn't mean you have to be calm. Hey, if you just got your ass chewed who wants to be calm? It is entirely possible to be angry and in control. I've done it many times. Your team is waiting to see how you react and they will react accordingly. That is when your leadership will stand out.
No matter what happened you have to take a step back and analyze the situation. Of course there are times when you need to make a quick decision, but usually things went off the rails way before that. Don't waste time trying to figure out who did it. Fix it first then worry about why it's wrong.
I remember we had a real bad inventory and the store managers kept the exhausted management team there for hours after it was over so they could figure out what happened, and how to fix it. It was pointless because they weren't going to come up with the solution right then. They were beaten and tired, so it made no sense trying to figure it out. He panicked.
Before you may any decisions get a handle on what's going on then map out the plan to fix it. There is no need to hit that dreaded panic button.
