The employment of married women is regarded as exceptional, but all large firms have a small number of such--3 or 4 per cent., perhaps. The usual practice is for girls to come from school and remain on until they get married or leave for some domestic purposes. Some come back as widows or when living apart from their husbands. Some firms boast a considerable number of workers who have been employed for very long periods, ranging from 15 to 30 years and upwards. There are no signs of married women lowering the rates of pay. It is customary for those who return after a long absence to do so at the old wages. Efforts have been made from time to time to organise the women into unions, but they have invariably proved disappointing. Indirectly the women have gained by the successful efforts of the men to shorten the hours of toil. Generally speaking the attitude of the men's unions is not so much one of hostility as of indifference to women's work, except where it threatens to encroach on the men's preserves. There is no positive agreement as to the line of demarcation; it is determined tacitly by use and wont. The men profess to see a tendency among employers to extend the field of female labour. This extension of woman's sphere they deprecate as likely to lead to the lowering of men's wages. Just as men are never employed in folding in the bookbinding department of a publishing firm, so certain processes are invariably never done by women. As a rule men do the heavier and more complicated work, while women do that which is preparatory or supplementary. In jobbing-shops where odd volumes come in to be bound in various styles women are unsuitable, and men do the work right through; but in large publishing houses where orders run into thousands women specialise on particular processes. Women's work is apt to be extended where there are large quantities involved and where the work can be sub-divided. While women perform many of these sub-divisions quite as skilfully as men, they do not exhibit a like concentration of effort, and are more inclined to scamp.
