Under Article VII, which deals with working hours, provision is made that the duration of a normal working day must in no case exceed eight hours for day work and seven hours for night work, and that the duration of a normal day, first, for persons under eighteen years of age, and second, for persons working in especially hard or health-endangering branches of industry, must not exceed six hours. In case the nature of the work is such that it requires a working day in excess of the normal, two or more shifts shall be engaged. Except in extreme cases work in excess of the normal hours, or what is usually called overtime work, is not permitted. No females and no males under eighteen years of age may do any overtime work, and the time spent by those on such work in the course of two consecutive days must not exceed four hours. All wage earners must be allowed a weekly uninterrupted rest of not less than forty-two hours, and on the eve of rest days the normal working day is reduced by two hours. Every wage earner who has worked without interruption not less than six months shall be entitled to leave of absence for two weeks, and every wage earner who has worked without interruption not less than a year shall be entitled to leave of absence for not less than one month with full pay. Article VIII deals with methods to insure efficiency of labor. The standard output for wage earners of each trade and group is fixed by valuation commissions of the respective trades unions. This article provides that a wage earner systematically producing less than the fixed standard may be transferred by the decision of the proper valuation commission to other work in the same group and category, or to a lower group or category with a corresponding reduction of wages. However, appeal can be taken from this provision of the law as well as all other provisions in the code. Article IX provides for protection of life, health and labor of persons engaged in any economic activity, and the carrying out of this part of the law is entrusted to labor inspectors, technical inspectors and the representatives of sanitary inspection. The labor inspection is under the jurisdiction of the People’s Commissariat of Labor and its local branches, which are the Departments of Labor, and is composed of labor inspectors, elected by the councils of professional unions. The inspectors are compelled under the law to visit at any time of the day or night all the industrial enterprises of their district and all places where work is carried on, as well as places provided for the workmen by the enterprises, such as rooming-houses, asylums, baths, etc., and to assist the trades unions and works committee in their efforts to ameliorate in individual enterprises as well as in branches of industry.
