In addition to their normal hours of work, electronic technicians at a power plant were required to remain “on-call” from 4:30 PM to 7:30 AM on Monday through Friday and for 24 hours on the weekend. While on-call, the technicians typically responded to 3-5 alarms per evening. Each alarm took, on average, about forty-five minutes of work. Technicians were expected to respond to alarms within 15 minutes. Failure to respond was grounds for discipline. The technicians were given pagers, but these did not work properly, forcing the technicians to remain at or near home. The technicians were paid for the time they spent actually responding to problems, but not for the remainder of the on-call time. The technicians sued for unpaid overtime. What should the court decide? Why?
