Working relations have experienced significant changes in post-industrial societies compared to traditional periods. Today, atypical employment models shape the labor market, including flexible employment formats, outsourcing, and various agency work such as staffing. The part or full-time employment model not dependent on a specific employer, described as "precarization," is becoming widespread and is the primary focus of this study. With precarization, unionized and organized labor is replaced by precarious working models, including working styles, mobile jobs, flexible working hours, and fixed-term employment contracts. These changes are reshaping labor relations in many countries globally, especially under the pressure of neoliberal theses. Precarization has caused a significant decrease in unionized employees, especially since the 1970s, which continues today. As a result of de-unionization, a new precarious class of precarious is emerging. The primary purpose of this study is to show the effects of the strategy of disorganization of labor on the "precariat" class, which has been described in recent years as the new social class. This is an empirical study based on secondary data sources. The secondary sources' findings show that a relationship between "precarization" and "disorganization of labor" can be established.
