Employee growth need strength (EGNS) is defined as a worker's need to obtain "growth" satisfaction from his work. The moderating influence of EGNS on relationships between global job satisfaction and the job attributes of conflict and ambiguity were investigated. Production supervisors (N=57) completed questionnaires on role perceptions, job satisfaction, and EGNS. Results from moderated regression analysis suggest that EGNS significantly influences the relationship between role-conflict and satisfaction, but does not significantly influence the relationship between role-ambiguity and satisfaction. Findings point out the importance of individual differences as a moderator of the relationships between job attributes and employee affective response. Results also contribute to the construct validation of the trait of EGNS. (Author/NRB)
