This paper examines how particular structural pressures external to th
e firm can combine with the internal micro-dynamics of workplace relat
ions and conflict to create a mode of labour regulation which correspo
nds to a 'Japanese style' teamworking rather than alternative, more au
tonomous models. It draws on both quantitative and qualitative case st
udy research data of the introduction of job reforms at a brownfield a
utocomponents factory in South Wales. The paper investigates three key
facets of the reform process. First, how the external factors of indu
strial restructuring and the forging of new customer-supplier relation
s between firms shape managerial priorities and organisational outcome
s. Second, how the microdynamics of workplace relations, in particular
, the different interests and actions of managerial, white collar and
shopfloor employees, have a direct bearing on the final composition of
teamworking. Third, in response to the lack of attention given to the
views of those who are most affected by job reforms, the paper provid
es a systematic analysis of the disempowering impact of teamworking on
shopfloor workers' labour processes.
