§ Mr. Nicholls
There are no data available on trade unions that enable a full answer to be given. However, there is information relating to the divisions of the standard industrial classification. The most recent data come from a specially commissioned survey of employees conducted for the Department in February and March 1989.657W
Regarding trade union membership, the survey showed that only in one division of the standard industrial classification—energy and water supply—does the level of trade union membership among employees exceed 75 per cent.
The survey also showed that in two divisions, over 75 per cent. of employees worked in establishments that recognised trade unions for purposes of collective bargaining. These are energy and water supply, and transport and communication.
