HC Deb 19 November 1928 vol 222 c1391
87. Commander BELLAIRS

asked the Postmaster-General whether he can give any figure as to the comparative size of staffs in regard to volume of traffic maintained on the British telephone systems and those of the American Telephone and Telegraph Company?

Viscount WOLMER

The relation of operating staff to the volume of traffic is very similar in the two systems, but the "values" given to the various classes of call differ slightly, and this makes exact comparison difficult.
