Job demands include sustained or intense physical, mental or emotional effort that is unreasonable or beyond workers' skills, and sustained low effort. High demands include long, irregular or on-call hours, short or interrupted breaks, no chance to recover or use leave, heavy workloads, hazardous manual tasks and fast paced work; mental demands such as complex tasks beyond capacity, long vigilance, high consequence of error, no systems to prevent individual error and constant task switching; and emotional demands such as de-escalating aggression or hiding emotions. Low demands include too little work, long idle periods, monotony and work well below skill. Example controls: schedule tasks to avoid sustained extremes and plan shifts for rest and recovery; manage supply chains to avoid demand swings; design the workplace to remove demanding tasks, provide quiet and break areas and use systems that reduce error; staff enough skilled people, roster for breaks, rotate demanding or repetitive tasks and support peaks; allow discretion to ease emotional demands; set achievable targets, train, and describe emotional demands in position descriptions and at selection.
