Question to the Department for Exiting the European Union :

To ask the Secretary of State for Exiting the European Union, what percentage of workers employed directly by his Department belonged to a trade union in each year since its formation.

The Department does not have a check-off facility for the deduction of trade union subscriptions from departmental employees pay, therefore a complete set of data to give an accurate figure for the percentage of employees who are trade union members for the period requested is not held by the Department.
