In the development of the systems of international labour law and EU labour law the author focuses on the field of employment relationship, working time, antidiscrimination law, atypical employment, decent work, termination of employment relationship by employer as well as elimination of the worst forms of child labour including prohibition of slavery, forced and compulsory work. The author deduces from a comparison of the examined systems some common law characteristics. One of them is the convergence of the development of both legal systems particularly in the field of atypical employment and working time. This is evident even if the substantive scope of atypical employment in the ILO legislation is significantly narrower than in comparison with EU law.

The level of EU anti-discrimination law, its substantive and personal range, is in comparison with ILO Conventions significantly higher. The termination of employment relationship from employer initiation is in ILO standardization on a substantially wider and more social level. In conclusion it can be said that among differentiating characteristics of the actual ILO standardisation and development of EU labour law, the areas of considerably wider material and personal scope belong to the ILO Conventions.
