This article examines the deep changes which have been observed in Fre
nch and Quebec firms as regards job relation regulation. A different e
merging social compromise can be distinguished from the one interioriz
ed by the collective actors since the Second World War. Whereas this c
ompromise, the Fordist compromise, depended on a correspondence betwee
n the type of job and the salary, the latter - which does not yet have
either the coherence nor the institutional support of the former - ha
s developed around a correspondence between productivity and the job.
Therefore, the notion of productive efficiency becomes a stake in soci
al regulation, leading to more advanced forms of related regulation.
