abstract="INTRODUCTION: Bullying and violence at work are relatively common in Finnish public sector workplaces. Previous research has demonstrated their association with increased risk of poor health and well-being, but only few intervention studies exist. The aim of this protocol paper is to describe the development and assessment of the effectiveness of a workplace intervention aimed at reducing these harmful phenomena. <br><br>METHODS AND ANALYSIS: This protocol describes a two-wave quasi-experimental intervention. Each of the three participating Finnish public sector organisations (cities) will select four work units (a total of 450-500 employees) to participate in an intervention including 2-3 workshops for the work unit, 2-3 consultative meetings with the supervisor of the work unit, a follow-up meeting for the entire work unit (a maximum of 6-month time lag) and online meetings with the supervisor to monitor achievements and discuss about difficult cases, if any. Three age-matched, sex-matched and occupation-matched controls for each participants of the intervention group will be randomly selected, a total 1350-1500 individuals in the control group. For intervention and control groups, premeasurement is based on responses to a survey that was conducted in 2020. Postintervention measurement will be based on survey responses in 2022. Data will be analysed using latent change score modelling or difference-in-difference analysis. ETHICS AND DISSEMINATION: Ethics approvals are from the Ethics committees of the Helsinki and Uusimaa hospital district and the Finnish institute of Occupational Health. <br><br>RESULTS will be made available to participating organisations and their employees, the funder and other researchers via open access article in a peer-reviewed journal and subsequent reporting of the results via social media channels and press release to the public.<p /> <p>Language: en</p>",
