 Lifeguards at the Rogers Aquatic Center operate in a shirt color-based hierarchy. Naturally, junior guards are at the bottom. After them comes the red shirt guards, who sit on the lifeguard stands and watch the water. Then there are the blue shirts, who facilitate breaks. Next are yellow shirts, who manage each attraction and the lifeguards assigned to them. Finally, black shirts make sure everything runs smoothly. Jacobson says this progression allows for an easier transition into leadership.
