I love this culture/attitude. With my team, I tell them that if I need to sweep the floors so that we can deliver...I'm grabbing a broom and sweeping the floor.
Every IT employee is a manager, no matter how high you rank is. James E. Casey(founder) recognized that technology will drive the company and technology employee are the one who make company operational 24/7.
If for some reason I (or any other manager) ends up at sorting facility and there is no one in charge, I must step in and take the charge of operations.
