This project explored the nature and functions of a range of informal networks developed by freelance workers to represent and defend their interests in the UK audio-visual (AV) industries. The structure of employment in this sector has changed considerably over the past two decades. Worker insecurity and uncertainty have developed as permanent jobs are replaced by freelance and short-term contracts. Over this period Trade Union influence and recognition has been eroded while the importance of networks based on informal contacts and reputation has increased. This project explores the ways in which freelance workers use networks to articulate and advance both individual and collective interests. The researchers interviewed 35 freelance workers, who were questioned on their individual behaviour, attitudes, and aspirations in relation to informal networks. They also conducted 7 interviews with key informants from trade unions and interest groups exploring the interaction between informal networks and traditional institutions of industrial relations. The principal objectives of the study were: to explore the use of informal networks by freelance workers in AV industries to examine how such networks are used to represent/defend worker interests in the employment relationship to assess whether such networks provide the potential for collective renewal and/or a foundation for alternative institutions to represent collective interests to investigate the impact of such networks on existing formal networks of representation (i.e. Trade Unions).
