An empirical study of work attitude, role efficacy and stress experienced in a high reliability professional group was undertaken using a sample of 52 Indian Air Traffic Controllers (ATC) working in the Mumbai Airport. Results showed that ATCs experienced role stress with regard to inter- role distance, role isolation, resource inadequacy, role erosion and role stagnation. ATCs maintained high confrontation or problem solving skills in their role followed by helping relationship, perceived integration with the job and managing well their inter-role linkages. Results further showed significant relationships between work attitude and role efficacy dimensions. Regression analysis within respective canonical variable sets revealed role stress being a significant predictor of attitude towards supervisors and management, while role efficacy dimensions (role making, role centering and role linking) showed significant explanatory power equally strongly with respect to attitude towards work, working conditions, co-workers, supervisors, and management.
