HC Deb 12 December 1980 vol 995 c496W
Mr. Nicholas Winterton

asked the Secretary of State for Employment what was the total number of working days lost through strikes involving 5,000 or more workers in 1979; and what is the number of days lost by the same criterion for 1980 so far.

Mr. Mayhew

The total number of working days lost through stoppages involving 5,000 or more workers in 1979 was 23,295,000.

Corresponding figures for part of the year are not compiled, but a rough estimate for the first three quarters of 1980 is about 10 million.
