Discussions about the position of British trade
unions under Thatcherism continue to interest
scholars and practitioners in the UK, and a variety
of theories have been put forward which suggest
that unions are becoming increasingly marginal to
workplace employee relations. Three of these are
focused on, namely, the roll‐back of union
organisation, the separation of collective bargaining
from strategic decision making, and the impact
of employee involvement on union activity. These
ideas are evaluated against data from a longitudinal
study of four multi‐plant private sector
organisations, each of which has high levels of
union density and some forms of employee
involvement. The data, which were collected in
the late 1980s, suggest that simple monocausal
correlations – such as employee involvement is
directly undermining trade unions – are not
robust enough to cope with the reality of
organisational life. Much more credence needs to
be given to the environmental and more broader
managerial context within which employee
relations takes place.
