asked the Secretary of State for Employment how many persons he estimates, in the light of the three-day working week, are protected fully or partially by a guaranteed week's pay ; how many are not protected, and if he will indicate their income distribution ; in how many cases their guaranteed pay, where it exists, is less than the income from three days' working ; and in how many of the remaining cases of guaranteed pay employers have retracted obligations to meet guaranteed pay.

The nature of the guarantee and the conditions under which it applies vary extensively, and the precise application of such agreements is often a matter for determination at plant level. Further work remains to be done in order to answer this Question comprehensively and I will get in touch with the hon. Member as soon as possible.
