HC Deb 22 July 1943 vol 391 c1045
4. Flight-Lieutenant Raikes

asked the Minister of Labour the age above which trade union officials are reserved against military service or direction into another civilian occupation?

Mr. Tomlinson

Trade union officials are not reserved from military service, but those whose retention on their trade union work is considered to be essential may have their calling up deferred. Officials over military age are not, under present arrangements, directed to other civilian work.
