Is there a need to introduce a presumption of an employment relationship into the Polish legal system?

The article contains reflections on the legitimacy of introducing the presumption of the employment contract’s labor law character into the polish legal system, the possible shape of such a regulation and the manner of its introduction in relation to the axiological assumptions of the labour law. The author joins the discussion on the presumption by referring to the views presented by legal scholars on the subject and analyzing the presumptions existing in the Netherlands, Switzerland, and Slovenia. In his conclusions, he supports the introduction of the presumption in material and rebuttable form.
