I have worked for and with so many people who simply could not control their cool. Some of them were scary to be around in high-stress scenarios and others were actually fun to get spun up. I watched wrenches, clipboards, coffee mugs, and many other objects fly across the room or flightline and even a couple people who began to dry heave. All because of stress. Now, everyone else on the plane or team was experiencing the same stress factors, we just had a different response. When you are leading a team and things begin to crumble, it is normal to feel stressed. It is normal to want to throw something, swear or whatever. However, you can’t let your team see this, because they are looking to you to be their rock. I bet the guy in the picture is stressed out; however, he knows he has to remain calm for his team.
