HC Deb 15 July 1969 vol 787 c69W
46. Sir F. Bennett

asked the Secretary of State for Emloyment and Productivity how many hours she estimates were lost to industry through unofficial strikes during the three weeks preceding 19th June and the three weeks subsequent to that date.

Mr. Harold Walker

Official statistics of stoppages of work due to industrial disputes relate to calendar months and it is impracticable to extract figures for other periods.
