Bennett has just been diagnosed with diabetes. He has the disease under control through diet, exercise, and drugs. He is an assistant manager at a chain department store, and he is fully capable of performing all of his job functions and needs no accommodations. Bennett rides a bicycle over 100 miles per week, participates in half marathons, and regularly works out at the YMCA. When he applies for a promotion to manage a store in the chain, he is turned down because his superiors are concerned that his diabetes could affect his job performance. Is Bennett disabled, and does the Americans with Disabilities Act afford him any protections?
