The standing orders are rules of conduct for workmen employed in industrial establishments and must include matters such as classification of workmen, working hours, attendance, conditions and procedure for obtaining leave, and the authority responsible for granting leave. The text of the standing orders as finally certified under this Act must be prominently posted by the employer in English and in the language understood by the majority of his workmen on special boards to be maintained for the purpose at or near the entrance through which the majority of the workmen enter the industrial establishment and in all departments thereof where the workmen are employed. The Act applies to every industrial establishment wherein 100 or more workmen are employed, and the Central Government is the appropriate Government in respect of establishments under its control or a Railway Administration or in a major port, mine, or oil field.
