HC Deb 18 January 1990 vol 165 c393W
Mr. Leighton

To ask the Secretary of State for Employment how statistics are kept on the number of days lost through unofficial strikes.

Mr. Nicholls

Separate statistics on unofficial strikes ceased to be published as a regular series in 1981. However, a limited amount of information from a special exercise was included in the Government's Green Paper "Unofficial Action and the Law", a copy of which is in the House of Commons Library.
