Using H. Dennis' (1974) five-factor communication climate construct framework as a predictor variable, a study investigated the relationship between perceptions of communication climate and job satisfaction of supervisory employees in the banking industry. A systematic random sample was drawn from 68 commercial banks in Orange County, California, during the late spring of 1985. Thirteen banks were selected for the study, and 137 supervisory personnel from those banks were surveyed (with a 71% response rate or 98 useable questionnaires). The questionnaire measured Dennis' five communication factors: (1) perceptions of superior-subordinate communication; (2) reliability of organization information; (3) supervisors' empathy for subordinates; (4) upward communication and influence; and (5) reliability of information from subordinates and peers. Job satisfaction questions examined compatibility with fellow employees, adequacy of immediate supervisor, satisfaction with their job as a whole, effectiveness of the organization, and satisfaction with economic rewards. The questionnaire was pre-tested among 30 supervisors at two banks in Orange County not included in the sample, and the minor changes recommended by the participants were incorporated. Results confirmed that positively perceived organizational communication is positively and significantly related to job satisfaction. Analysis also revealed a positive link between organizational trust and influence. A major contributor to supervisors' job satisfaction was their communication with top management and their ability to influence workplace decisions--not their communication with immediate supervisors.
