The importance of non-standard employment forms has increased over the last decades. Janine Leschke addresses two important questions in this regard. First, do workers with part-time and temporary contracts face greater risks of becoming unemployed than those with regular contracts? Secondly, how far are they disadvantaged in terms of access to and level of unemployment benefits? The author compares the design of unemployment benefit systems in Denmark, Germany, Spain, and the United Kingdom. After discussing the development and role of non-standard employment in these countries, she examines the relevant features of unemployment insurance systems such as hours and earning thresholds and minimum contribution requirements. Her empirical analysis shows that non-standard workers are more likely to become unemployed or inactive and are disadvantaged in their entitlements to unemployment benefits.
