This is of more than theoretical interest in Denmark (where the study was done), because both public and large private employers have a mandatory health-and-safety oversight process, which needs to be guided by some solid facts about what actually contributes to health and safety. The typical setup is that health/safety statistics from various sources (like the health-care system) are collected and cross-referenced with employment, and if a workplace or department is an outlier on any of those (e.g. significantly above-baseline levels of new mental-health visits), the information is presented to a standing committee made up of both management and employee representatives, which is tasked with investigating why this is the case, and coming up with a plan to address the issue.
