Numerous studies have shown that 12-hour shifts, rotating shifts, and unpredictable work schedules are associated with greater risk of chronic health conditions including mental illness, cardiovascular disorders, gastrointestinal disorders, and obesity. Although large manufacturing companies recognize the risks, they cite several arguments in favor of maintaining them, including the 24/7 production schedule, and in some cases, employee preferences for long shifts to maximize days off and pay.
