HC Deb 09 February 1977 vol 925 c670W
Mr. Arthur Lewis

asked the Secretary of State for Energy whether he will have investigations made to ascertain to what extent fuel and other costs would be saved if a four-day working week were introduced.

Dr. John. A. Cunningham

No. Net energy savings arising from a rearrangement of the working week would be unlikely to be big enough to be a significant factor in any such decisions.
