The article is devoted to the problem of identifying significant indicators of precarious employment and their priority, the solution of which was based on the authors: 1) checking indicators for multicollinearity, for which, based on the processing of data from the Federal State Statistics Service and The Russia Longitudinal Monitoring Survey - Higher School of Economics (RLMS-HSE), an array of data was generated for the period 2010-2020; 2) checking indicators based on expert assessments of Russian specialists collected in 2022 during a survey specially organized by the authors. Taking into account the integration of the verification results by two methods, the indicators of the initial list proposed by the authors were clarified and verified and the final list of indicators of precarious employment was formed. The final list includes indicators that make it possible to identify objective (taking into account the assessment of the type of registration of employment and employment conditions) and subjective (taking intoaccount the assessment of the presence of instability of the labor situation and dissatisfaction with employment and its conditions) manifestations of precarious employment in relation to Russian conditions. The prioritization of indicators of precarious employment was carried out and three groups of indicators were identified by priority level to characterize its manifestations: with a high (key indicators), medium and below medium priority level. The boundary for the indicator of the level of income from basic employment, which does not ensure the stability of the financial situation of households, has been clarified. It was revealed that precarious employment, regardless of the type of employed households, is identified by income from basic employment, which does not allow per capita income to be brought to the level of standards that form middle and higher material security (3.1 of subsistence minimum and higher).
