Our nation started the working conditions inspection in 1933. the present working conditions inspection is mainly based on its grevances submited by workers or unions, covering 17 key inspection items, including engaging child workers to do burdensome and dangerous work' illegally extending working time; failure to follow legal requirements to appropriate money into the employees' welfare funds; failure to follow legal requirements to join labor insurance for workers, etc. Up to now, the emphasis of labor inspection in Taiwan has largely been on the enforcement of legal provisions in the area of workers' safety and health, and less to the application of legislation on working conditions. In order to improve the system of working conditions inspection, five suggestions are proposed: exteding the sciope and items of present working conditions inspection; raising the ad hoc working conditions inspection teams to be a formal and regular inspection group; establising enterprises; increasing working conditions inspection for drivers, pilots, construction workers, etc.; requesting the inspectors to give advice to employers and unions how to abide by the labor standards laws advice to employers and unions how to abide by the labor standards laws and to authoritative government agencies how to reform related regulations.
