This paper considers the rapid decline in unionization that has occurred in
Britain since the late 1970s. The overwhelming factor underpinning falling
unionization was a failure to organize new establishments set up in the la
st twenty years or so, thus confirming that developments since 1990 represe
nt a continuation of the pattern revealed in earlier work for the 1980-90 p
eriod. The sharpest falls in unionization occurred in private manufacturing
establishments set up after 1980. Finally, there is some evidence that it
is age of workplace, rather than age of worker, that is the critical age-ba
sed factor behind union decline.
