HC Deb 05 April 1984 vol 57 c620W
Mr. Terlezki

asked the Secretary of State for Employment what information he has as to the average pay of a non-union worker and a worker who is a member of a trades union.

Mr. Gummer

No official surveys of pay inquire about the union status of workers. There is, therefore, no information on the average pay of a non-union worker and a worker who is a union member.
