1996 to expand the scope of application of the Labor Standards Law, the Labor Standards Law apply to more industries and workers are increasing given the first 84-1, the scope of the special nature of the work of labor Narulaoji France occasion, exclude the hours of work subject to the restrictions. Security Services security guards approved Notice in accordance with the Council of Labor Affairs in 1987, the Labor Standards Law Article 84-1 of the workers, the working hours by the employer and employee agree otherwise, without the restrictions of the relevant provisions of the Labor Standards Law. However, because of the security personnel who work long hours caused a lot of controversy and doubt, the CLA then amended on December 17, 1999 Occupational precipitating cerebrovascular and heart diseases (except for trauma cause) of the identified reference guide, and 100 in May set the security personnel of the security industry, working time audit Reference Guide, ”local government aid guidelines set out by the review of the base of the engagement letter for approval Section 84-1 of the Labor Standards Law.
