This study focuses on strike activity during the 1950–1969 period in ten industrial societies, The first section of the paper deals with issues of strike measurement and introduces a three-dimensional characterization of strike activity which forms the basis of the subsequent statistical analyses. The next section examines postwar trends in industrial conflict in order to evaluate the argument that strike activity is “withering away” in advanced industrial societies. Time plots of the aggregate volume of industrial conflict show that there has been no general downward movement in strike activity during the postwar period.
The third part of the paper develops a number of theoretically plausible statistical models to explain year-to-year fluctuations in the volume of strikes. The empirical results of this section indicate that (1) there is a pronounced inverse relationship between strike activity and the level of unemployment, which suggests that on the whole strikes are timed to capitalize on the strategic advantages of a tight labor market; (2) industrial conflict responds to movements in real wages rather than money wages, which indicates that labor is not misled by a “money illusion”; (3) Labor and Socialist parties are not able to deter strike activity in the short-run despite their strong electoral incentive to do so; and (4) the volume of strikes does seem to be influenced by the relative size of Communist parties, which suggests that such parties remain important agencies for the mobilization of discontent and the crystallization of labor-capital cleavages.
