The problem treated in the paper is the phenomenon of "working poor". The increasingly widespread approach to the phenomenon of "poor workers", "work poverty" is determined by the increase in "work poverty" rates, including in the context of recent economic crises. The official profile and measurement of the "working poor" differs from one country to another, and the official statistics of the Republic of Moldova do not provide such data. At the same time, when developing inclusive and sustainable social policy, it is vital to design measures that would contribute to support the category of working poor, increase opportunities for qualification and adequate education, the possibility of increasing incomes, access to health services, access to social housing etc. The paper presents a differentiated treatment of the "working poor" with aspects specific to developed and developing countries. The latest data from international statistics on the "in-work poverty rate" and relevant information provided by national statistics are presented. The authors formulated conclusions aimed at promoting knowledge and treatment of this phenomenon, present some sensitive areas of the "working poor" problem in the Republic of Moldova, solutions for supporting employees classified as "working poor".
