This article discusses whether self-employed and platform workers in Denmark have effective access to the unemployment insurance scheme. The Danish case is intriguing in a comparative context. Unlike other European States, it has been possible in Denmark for the self-employed to formally access the unemployment scheme since 1976. The system is also interesting as it is rather flexible, and was recently adapted to meet the challenges of changing work patterns and an increase in atypical forms of work, such as platform work. Yet, it is argued that important barriers to effective coverage remain. Some barriers, such as the voluntary character of the insurance and its eligibility criteria, are common to all persons with low and irregular work. Other barriers are specific to the self-employed and relate to the conditions for proving the closing down of business, and to waiting periods.
