Previous research has found inconsistent results on the impact of work-status (permanent vs. fixed term vs. causal work) on attitudinal and behavioural outcomes. This study explored this topic from a social identity perspective and examines the effect of communication climate, organisational and team identification on job-affective well-being, organisational commitment and intentions to recommend. In Study 1, 631 professionals working in Chile completed our survey. In Study 2, which was pre-registered, 520 professionals from the UK completed the same survey. In both studies we conducted multi-group path analyses comparing employees with three work-statuses: permanent, fixed-term, and casual workers (Study 1: n = 369, 129, and 131, respectively; Study 2: n = 438, 53, and 34, respectively). We found work-status influenced the relationship between organisational and team identification with job-affective well-being, but not with organisational citizenship behaviour or intentions to recommend. Across all groups, communication climate was an important predictor for identification measures, job-affective well-being and intention to recommend. These findings offer an understanding of the dynamics of social identification in the workplace that are related to work-status in the context of two different countries; Chile, a country that is characterised by high rates of fixed-term and casual job agreement and the UK, which has comparatively fewer non-standard work-arrangements.
