Summary
"In an effort to comprehensively address the many potential effects of CWWs in policing in a systematic way, the Police Foundation conducted an experiment in which officers were randomly assigned to shifts (8-, 10-, and 12-hour). We examined the independent effects of shift length, taking into consideration the time of day worked and the variations associated with specific agencies. Because past studies have tended to focus on a limited number of potentially important managerial and individual considerations, we examined a broad array of outcomes important to the officers themselves and the organizations, including officer stress, sleep, fatigue, health, and quality of life, off-duty employment and overtime, and a variety of performance and safety measures. In this report, we begin by presenting the key findings of our experiment and then describe the methodology, the comprehensive array of measures employed, and the results of the analyses conducted in the experiment. Subsequently, we examine cross-industry research on compressed workweeks, including that from policing and its connection to our findings."--Introduction.
