- ItemJob insecurity and affective organisational commitment : development and empirical evaluation of two structural models(Stellenbosch : Stellenbosch University, 2022-12) Tarr, Sally; Gorgens, Gina; Stellenbosch University.

Dept. of Industrial Psychology.ENGLISH SUMMARY: Job insecurity is a stressor that has numerous harmful consequences for both an individual and an organisation. The main objective of this study was to develop and empirically test two structural models, each depicting a possible nomological net of predictors explicating the relationship between cognitive job insecurity and affective organisational commitment, being mediated by affective job insecurity, by including various moderators affecting the mediated relationship. A greater understanding of the psychological processes that explicate the job insecurity and affective organisational commitment relationship could aid organisations in the South African environment to better understand the phenomenon of job insecurity and affective organisational commitment. The study made use of a non‐experimental quantitative research design to explore the relationships that exist amongst the variables (model 1: cognitive job insecurity, affective job insecurity, work centrality, optimism, and affective organisational commitment; model 2: cognitive job insecurity, affective job insecurity, employability, optimism, and affective organisational commitment). The sample included 154 participants that were selected though convenience sampling. The results of the analysis (conducted with PLS) provided sufficient evidence that of the two models, the constructs in model 2 provided a better explanation of the variables explicating the cognitive job insecurity, affective organisational commitment relationship, when being mediated by affective job insecurity. In summary, in model 2, six out of the eight paths were statistically significant, whereas in model 1, three statistically significant paths were obtained. The moderating effect of employability in the cognitive job insecurity, affective job insecurity relationship in model 2 was statistically significant. This is in contrast to the statistically insignificant moderating effect of work centrality in model 1. Additionally, a trend in the data existed across both models which suggested that optimism may buffer the negative effect of affective job insecurity on affective organisational commitment. Furthermore, the results provided support for the mediating role of affective job insecurity in linking cognitive job insecurity and employee outcomes. From the results, this study proposes various interventions that could be used to combat andreduce an individual’s negative experiences of job insecurity and thus it may increase their affective organisational commitment.
