The aim of this paper is to examine the relationships between three domains of job insecurity, namely job loss insecurity, insecurity regarding working conditions and labor market insecurity, taking into account both their cognitive and affective components. Relationships with other related factors such as worker's sociodemographic characteristics, household economic circumstances and occupational factors related to job insecurity are also shown. In order to achieve this we have used log-linear models and multiple correspondence analysis. By considering three domains and two components of perceived insecurity simultaneously, relevant aspects not previously observed of the relationships between them and related factors are revealed. This cross-sectional study of the wage-earning population in Spain in 2016 introduces therefore an element of complexity in the discussion on job insecurity which it would be advisable to incorporate in future research.
