HC Deb 20 November 1973 vol 864 c366W
Mr. Bray

asked the Secretary of State for Employment what is the number of domestic or localised strikes and days lost as a result thereof in shipyards and other constructional yards, manufacturing oil rigs and complementary oil exploration or handling equipment, in the last 12 calendar months to the latest convenient date.

Mr. Dudley Smith

The official series of statistics of stoppages of work is compiled on the basis of the Standard Industrial Classification 1968, which does not separately identify the manufacture of oil rigs and ancillary equipment. I regret, therefore, that the information is not available.
