The Health of Munitions Workers Committee has, since its inception, investigated at factory after factory such questions as the employment of women, hours of labour, Sunday labour, juvenile employment, industrial fatigue, canteen equipment, the dietary of workers. It has published its conclusions in memoranda, stripped bare of officialism, so as to reveal with frankness facts acquired by scientists in touch with reality. Working in connexion with this Committee is the Welfare and Health Department of the Ministry of Munitions. It follows closely the suggestions of the experts, its Welfare officers moving up and down the country, now offering a suggestion to the management of a factory, and again, assimilating some practical experiment in Welfare work, originated by a progressive factory-directorate. Thus, a pooling of ideas is being effected, and isolated experiments of value are now being propagated throughout the country. But possibly one of the most valuable tasks of the Welfare and Health Department is the selection and training of candidates for the work of Welfare Supervision in the factories. A panel of approved candidates is kept in readiness, so that a busy factory-manager may have at hand a choice of Welfare workers who will, if necessary, undertake the entire supervision of the personal interests of his female, or juvenile staff. These officers, after engagement by the factory management, are responsible solely to the firms that employ them and not to the Ministry of Munitions. In establishments where T.N.T. (Tri-nitro-toluene) is handled, the presence of a lady Welfare Supervisor is compulsory; in all National factories such an officer is recognized as a necessary part of the staff; and in Controlled Establishments, where a number of female operators are employed, the management is officially encouraged to make such an appointment. In many cases, engineering shops are for the first time employing female operators, and the management depute with relief all questions as to the personal requirements of the 'new labour' to the lady superintendent; in other instances, such matters as the engagement of the employees, canteen arrangements, and so on, are placed in the hands of other officials. Hence, the duties of the lady Welfare Supervisor differ from factory to factory. Generally speaking, the supervisor, or lady superintendent within the factory is made responsible for some, or all, of the following matters: 1. She aids, or is entirely responsible for, the selection of women, girls, and boys for employment. 2. The general behaviour of the women and girls inside the factory falls under her purview. 3. The transfer of a woman employee from one process to another is suggested by the Welfare Supervisor where health considerations make such an alteration advisable. 4. She is consulted on general grounds with regard to the dismissal of women and girls.
