Artikel 3

1. This Convention applies to all part-time workers, it being understood that a Member may, after consulting the representative organizations of employers and workers concerned, exclude wholly or partly from its scope particular categories of workers or of establishments when its application to them would raise particular problems of a substantial nature.
2. Each Member having ratified this Convention which avails itself of the possibility afforded in the preceding paragraph shall, in its reports on the application of the Convention under article 22 of the Constitution of the International Labour Organization, indicate any particular category of workers or of establishments thus excluded and the reasons why this exclusion was or is still judged necessary.
