Effects of task performance and contextual performance on systemic rewards.

Evidence from 2 samples of Air Force mechanics supported the hypothesis that contextual performance affects employees' career advancement and rewards over time. Results of hierarchical regressions controlling for experience showed task performance and contextual performance each predicted systemic rewards. Each facet explained separate variance in promotability ratings over 2 years. In both samples, contextual performance explained separate variance in informal rewards but task performance did not. Task performance explained incremental variance in career advancement 1 year later but contextual performance did not. Analyses using correlations corrected for unreliability suggest these results cannot be attributed to measurement error. Contextual performance still explained separate variance in informal rewards, and task performance explained distinct variance in career advancement a year later.
