Precarious work: from theoretical attributes to a proposed measurement instrument

Precarious work is a reality that has spread and become a global phenomenon. Although there is no consensus on the definition, it can be described as unstable, insecure work characterised by the limitation of the worker's power vis-à-vis employers or customers. It is therefore a multifaceted, complex phenomenon, the analysis of which requires a clear delineation of its components. This study aimed to develop a subjective measurement instrument from a theoretical framework for precarious work with satisfactory validity indexes. The study was conducted with data collected from two samples, one of Brazilian workers and the other of Mexican workers. While in the first sample the internal structure of the instrument was investigated and validity evidence for the three retained factors was identified, evidence of model fit was obtained in the second sample. The findings demonstrated the adequacy of the three factors: Feelings of Vulnerability (α=0.84); Reward Adequacy Ratings (α=0.90); and Perceptions of Exercising Rights (α=0.83). The fit indexes obtained (CFI=0.96; TLI=0.95; RMSEA=0.06) revealed the suitability of the instrument and together provided evidence of the theoretical-empirical relevance of the proposed measurement instrument.
