Stress has become a part of everyday life. Teachers are more prone to stress because dealing with students and caring for their better performance throughout the day is itself a stressful situation. The increasingly demanding nature of their jobs has also increased pressure levels dramatically. Stress is not an illness, but it is a condition that can give rise to very illness. A study was conducted to compare the Government and Private Secondary School teachers of different academic streams viz. languages Mathematics and Science and Social Science of Chandigarh with respect to Occupational stress. 600 secondary school teachers from Chandigarh, India have been selected as a sample and data was collected through descriptive survey method by using Occupational Stress Index developed by AK Srivastava and AP Singh (1992).
