This dissertation presents empirical evidence for the UK context on the effect of ICT use and involvement practices on the design of work. Besides those determinants, this work additionally scrutinizes another factor of work design mentioned at best on a passing note: trade union presence. The theoretical model applies a multidisciplinary perspective integrating insights from the task literature but also from organizational studies and from the field of industrial relations. Using data from the British Skill and Employment Survey Series for the years 1997, 2001, 2006, and 2012, the empirical analysis offers robust results indicating that union presence is associated with more tayloristic jobs involving less autonomy, lower relevance of problem-solving, and more control. In line with theory, the union effect moves in the opposite direction to the effect of ICT use and involvement practices. These results imply that the role of trade unions in the UK must be reconsidered in the field of British IR, and, at best, stipulates future research that evaluates in more depth the impact of labor representation bodies on the design of work.
