HC Deb 16 December 1981 vol 15 c146W
Mr. Hill

asked the Secretary of State for Employment how many working hours have been lost by disputes in ports covered by the dock work regulation scheme so far in 1981.

Mr. Waddington

The information is not available in the form requested. The National Dock Labour Board advises me that between 1 January 1981 and 4 December 1981 89,736 working days were lost in the 80 ports covered by the dock work regulation scheme.
