BackgroundWorking systematically with the work environment, particularly the organizational and psychosocial work environment entails several challenges for employers. There is a lack of knowledge on how to best undertake this work. Thus, the aim of this study is to evaluate the process of a six-year organizational-level intervention program where workplaces could apply for additional funds to implement preventive intervention measures, with the intention of improving working conditions and reducing sickness absence within the Swedish public sector.MethodsThe program management process was studied using a mixed-method approach combining qualitative document and content analyses based on process documentation produced between 2017 and 2022 (n = 135), interviews with internal occupational health services professionals in 2021 (n = 9) and quantitative descriptive analyses of submitted applications with decisions from 2017 to 2022 (n = 621).ResultsQualitative analyses of the process documentation revealed concerns from the project group regarding access to sufficient competence and resources among stakeholders and participating workplaces, and role conflicts and ambiguities between the program and everyday operations. To address these challenges, the application process was developed over time using the knowledge gained from previous years. A change in the mental models in work environment management, from an individual to an organizational perspective, was seen among the project group and the internal occupational health services responsible for implementing most of the granted intervention measures. In addition, the proportion of granted intervention measures on an organizational level increased throughout the years from 39% in 2017 to 89% in 2022. The changes in the application process were believed to be the main contributor to the change among the applying workplaces.ConclusionsResults indicate that a long-term organizational-level workplace intervention program may be used, by the employer, as a tool for shifting from an individual- to an organizational perspective in the work environment management. However, additional measures on multiple levels need to be implemented to secure a sustainable shift in perspective within the organization.
