Abstract
Stress research has widely documented how uncertainty represents a strong stressor that, in general, is negatively associated with well-being. While the literature on job insecurity about this topic is extensive and exhaustive, empirical research on the outcomes of life uncertainty, namely the perception and feeling of precariousness regarding the present and future of one's own life, is yet to be fully explored. In the present paper, we aimed to investigate the relationships among job insecurity, life uncertainty, and psychosocial well-being outcomes, specifically, with a focus on job satisfaction and burnout. The participants were 357 workers (M = 146 and F = 211), with an average age of 41.78 y.o. (SD = 13.49), who completed an online questionnaire containing, in addition to sociodemographics information, measures of the study variables, namely job insecurity, life uncertainty, job satisfaction, and burnout. The results pointed out negative relationships of both job insecurity and life uncertainty with individual well-being, as they were negatively associated with job satisfaction and positively related to burnout. In a path analysis with latent variables, life uncertainty proved to fully mediate the relationship between job insecurity and psychosocial well-being.
