Despite increased demand for police services, shrinking budgets have made it difficult for police departments to meet their staffing needs. As a result, police agencies throughout the U.S. have adopted variations on the traditional five day, eight hour work schedule. According to Shiftwork Solutions, smaller departments often set minimum staffing levels but find this does not effectively address their real, and variable, staffing needs. Instead, busy periods can be understaffed while other periods are overstaffed. While many police departments use 10-hour and 12-hour shift lengths, most jobs can be performed equally well on short and long shift patterns as long as the total number of hours remains the same.
