The intervention consists of two components: 1. Implementation of the GLAD intervention to the workers at one unit at the participating workplaces. The GLAD intervention consists of 15 modules containing knowledge on pain, participatory ergonomics and physical exercises. Each module last 30 minutes and are delivered by an occupational safety and health professional (OSH). 2. Education of the OSH's to deliver the GLAD intervention. The education aim to give the OSH the necessary knowledge, skills and competencies to deliver the intervention to the workers at their workplaces.
