(1)Where it is proved to the satisfaction of the Secretary of State that the customs or exigencies of the trade carried on in any class or description of factories require some other day in the week to be substituted for Saturday as the short day, he may, by regulations, grant to factories of that class or description a special exception authorising the occupier of every such factory to substitute some other day for Saturday, and in that case this Part of this Act shall apply in the factory as if the substituted day were Saturday, and Saturday were an ordinary work day.
(2)Regulations made under this section as respects newspaper printing offices, or as respects factories in which the work by reason of the nature thereof requires to be carried on on six full working days in the week, may authorise the substitution of some other day for Saturday in respect of some of the women and young persons employed therein.
