The Law defines part-time workers as "those who work shorter weekly scheduled hours than regular workers employed at the same establishments". It does not apply to the public sector (see article 32.). Under article 3, employers are required to endeavour to promote effective utilisation of the abilities of part-time workers, with due consideration of their actual work conditions and the balance with full-time workers, by taking effective measures in order to secure them proper working conditions and improve their management.

Under the Law, employers should endeavour to promptly issue documents concerning working conditions when hiring and, in preparing or modifying office regulations, to hear from the representatives of the majority of part-time workers. Employers should also endeavour to appoint a specific manager with responsibility for part-time workers where there are over a prescribed number of them. There are also provisions requiring the Government to promote the human resource development and training of part-time workers, and to provide them with employment information and services, including Part-Time Work Support Centres.

The Law does not incorporate penal provisions for employers who violate the Law, but gives a legal base for "Guidelines for Employers on Improving Employment Management of Part-time Workers" (see article 8) and requires the Minister of Labour, employer organisations and government to give employers relevant advice, guidance or to give recommendations as required (see article 10.).
