HC Deb 21 June 1927 vol 207 c1646

asked the Secretary for Mines if he has any information to show whether the multiple shift system has been extended in coal mines since the stoppage of 1926?

Colonel LANE FOX

I have no statistical information on this subject relating to the present year. But, speaking generally, I should say that the circumstances of the industry since the stoppage have not been favourable to the extension of multiple shifts.
