Kategoria pracy produkcyjnej i nieprodukcyjnej
In the article the author interprets the Marxist category of productive and unproductive work. She proves that from among three interpretations of this category uppearing in Marx' works, the interpretation being neutral in relation to work contents and based on social production relations is the most important interpretation reflecting not only the contents but also the spirit of Marx' works. This analysis is summed up by the author with a statement that productive work in Marx' approach is work determining optimization of the function of the economie activity target. Thus for each production system, being characterized with a different target of economic activity, the category of productive work changes its scope.
