It is widely assumed that shopfloor restrictive practices were both pe
rvasive and very damaging in post-war British industry. Indeed, this p
oint has been repeated by both politicians and academics, receiving pe
rhaps its most sophisticated exposition in the work of Mancur Olson. H
owever, a review of the contemporary evidence reveals that such an int
erpretation is almost wholly erroneous. Some commentators made much of
restrictive practices in the 1940s and 1950s, but their accounts are
hardly convincing. On the other hand, a range of more comprehensive en
quiries into the problem consistently showed that it was of limited im
portance. Serious restrictionism, in fact, was confined to a very few
sectors - the printing industry, the docks and shipbuilding - and cann
ot, anyway, be explained simply in terms of labour intransigence. Thes
e facts clearly need to be incorporated in future accounts of Britain'
s post-war industrial decline.
