This book presents conceptual tools and theoretical perspectives that can be used to sociologically analyze labour markets in modern capitalist societies. It makes use of the rich heritage of sociological thinking and draws on the classical work of Marx, Weber and Durkheim as well as structural-functionalist contributions. Contemporary sociological thinking is criticized for its tendency to exaggerate change in labour markets while the need to consider continuity is emphasized. Conceptual tools and perspectives are applied based on concrete phenomena, as the author combines abstract theoretical reasoning with theoretically founded reflections on actual labour market developments.
