The maximum working-day is thus the "general working-day" when applied to all industries without exception. When this is not the case, it is the restricted working-day, which may also be called the factory maximum working-day, as it really obtains only in factory and quasi-factory labour. The term factory working-day is further limited in its application in cases where its protection extends, not to all the labourers in the factory, but to the women and juvenile workers only, or to only one of these classes. Hence a distinction must be drawn between the factory working-day for women and children, and the maximum factory working-day extended also to men. We shall therefore not be wrong in speaking of this as the working-day of women and juvenile workers, nor shall we be putting any force on the customary usage, if by factory working-day we understand the working day prescribed to all labourers in a factory. We shall find a further limitation of the meaning in considering the aim of the protection afforded, for in certain cases the maximum working-day, even when extended to all labourers employed in a factory, is restricted to such occupations in the factory as are dangerous to health. In such cases, it might be designated perhaps the hygienic working-day. The maximum working-day, in the sense of the furthest reaching and therefore most hotly contested demands for regulation of time, means the uniform maximum working-day, fixed by legislation nationally, or even internationally, and not the maximum working-day of factory labour merely, or of female and child-labour in factories, nor the hygienic working day. This working-day is authoritatively fixed--provisionally at 10 hours, then at 9 hours, and finally at 8 hours--as the daily maximum duration of working-time, in the Auer Motion (Sec. 106 and 106_a_, cf. Sec. 130). Section 106 (paragraphs 1 to 3) runs thus: "In all business enterprises which come within this Act (Imperial Industrial Code), the working-time of all wage-labourers above the age of 16 years shall be fixed at 10 hours at the most on working-days, at 8 hours at the most on Saturday, and on the eve of great festivals, exclusive of intervals of rest. From January 1st, 1894, the highest permissible limit of working time shall be fixed at 9 hours daily, and from January 1st, 1898, at 8 hours daily." According to the same section, the 8 hours day shall be at once enforced for labourers underground, and the time of going in to work and coming out from work shall be included in the working-day. "Daily work shall begin in summer not earlier than 6 o'clock, in winter not earlier than 7 o'clock, and at the latest shall end at 7 o'clock in the evening."
