HC Deb 21 April 1970 vol 800 cc85-6W
43. Sir F. Bennett

asked the Secretary of State for Employment and Productivity how many working days were lost to industry through unofficial strikes during March, 1970.

Mr. Harold Walker:

Separate estimates are available only for stoppages known to have been official. The great majority of the remainder would have been unofficial. The provisional total for March, 1970 of working days lost in the United Kingdom in all stoppages in progress is 815,000, of which 59,000 were lost in stoppages known to be official.
