Prevent is a nonprofit association in the work environment field with the Confederation of Swedish Enterprise, the Swedish Trade Union Confederation (LO) and the Council of Negotiation and Cooperation (PTK) as principals. Our task is to work together with our principals to share knowledge of work environment issues and to develop methods that can support every workplace in the routine management of the work environment. Prevent's general and sector adapted materials, checklists and other instructional aids make it easy to go from theory to practice. We run training sessions on work environment issues throughout Sweden. We offer open sessions, company specific training and web based training.
