Store managers at a gasoline station/convenience store chain earn a base salary of $522/wk and are eligible for a bonus that can bring their pay to a maximum of $2,500/month. Managers work at least fifty hours per week and are on call 24/7. They spend about 60 percent of their time performing nonmanagerial tasks such as stocking shelves, operating registers, and cleaning bathrooms. Store managers also perform managerial tasks, including supervising employees, hiring, training, scheduling, and disciplining employees. Store managers recommend pay increases and terminations to district managers, but they do not decide these matters unilaterally. District managers typically visit stores once or twice a week and communicate frequently with store managers via phone and e-mail. Are the store managers exempt executives?
