This paper exploits the Workplace Industrial Relations Survey from 199
0 (WIRS3) to examine the determinants of workplace injuries for a samp
le of manufacturing establishments in the UK. A key focus of this pape
r is an assessment of the role played by union-appointed safety repres
entatives and joint health and safety consultative committees in reduc
ing the frequency of workplace accidents. We find that joint consultat
ive committees, with all employee representatives appointed by unions,
significantly reduce workplace injuries relative to those establishme
nts where the management alone determine health and safety arrangement
s. However, an important role is also found for those joint consultati
ve committees where no employee representatives are appointed by union
s.
