Trade unions and contingent labour: scale and method

In recent years, there has been a trend for trade unions to attempt to represent contingent workers, including agency staff, workers on fixed-term contracts and the self-employed. This article seeks to explain and characterize this development in the UK. The main conclusions are that contingent workers require an "upscaling" of union representation, beyond the workplace, and that methods other than collective bargaining are more important for advancing the interests of this group. These methods include attempts to regulate labour markets unilaterally, provide union services and make use of employment law. Copyright 2009, Oxford University Press.
