Exemption was asked for a skilled mechanic, by the owner of a cork manufacturing business in Colliers Wood. The employer said the man was very valuable in his present employment and he will be practically impossible to replace. A large proportion of their manufacturers were for government uses. He employed about 17 men of whom are only three were eligible. He pleaded that his son was capable of doing almost anything in the business and his departure might cause the closing down of the business.
Three months exemption.
