In a recent study of 1,500 business managers in the United States, interviewers asked all kind of questions about the manager's habits and opinions regarding their working hours. The researchers learned that only 33 percent of the managers worked 40-45 hours a week. The majority of them (57 percent) worked from 46-60 hours and 6 percent worked over 60 hours. Only 2 percent of the managers said they felt satisfied and had enough time to do everything. The rest of the managers felt they did not have enough time for their families or their hobbies. In general, the researchers found that managers in the United States are not happy with their working schedules.
