This chapter focuses on the mechanisms by which workers, unionized and non-unionized, are represented at work, and through which they obtain varying degrees of voice in employer decision-making. In addition to collective bargaining by trade unions, it highlights the mechanisms of information sharing and joint consultation. One argument is that an understanding of the interaction of these representative mechanisms is important for an appreciation of the present and likely future patterns of worker representation in the UK. Specifically, it suggests that forms of representation other than collective bargaining may in future prove more popular voice mechanisms – with both employers and employees – than they have in the past.
