During the last few inflation-ridden years many countries have experienced a severe crisis of industrial relations as workers tried, through collective action, to preserve their living standards against the pressure of rising prices. But Tanzania stands as a conspicuous example of one country where, during the 1970s, strikes seem virtually to have disappeared, as may be seen from Table I.1 It is true that the Tanzanian definition of a strike excludes disputes lasting less than one day; and it is also true that there have been occasions since 1972 when workers have 'downed tools' for brief protest periods. But the lack of reported strikes in Tanzania is not a statistical illusion. The Labour Officers of the Ministry of Labour and Social Welfare keep a close watch on the state of industrial relations, and these occurrences are known to and are reported by them, as is shown by their recording of three strikes in 1977. This last fact also demonstrates that strikes can still occur in Tanzania.
