The present study was carried out to assess job satisfaction of tribal and non tribal school teachers of Chhattisgarh comprising both the sexes. To conduct the study 60 primary school teachers of tribal origin (Ave. age 32.16 yrs.) and 60 primary school teachers of non-tribal origin (Ave. age 31.16) were selected. While selecting the sample, equal weightage was given on the basis of gender. Purposive sampling was used in the present study. To assess job satisfaction, JSS prepared by Singh and Sharma (1999) was used. Analysis of data with the help of 2x2 factorial ANOVA yields significant main effect of tribal, non-tribal belongingness as well as gender on job satisfaction of primary school teachers. The two factor joint action effect of tribal, non-tribal belongingness and gender on job satisfaction was not found to be statistically significant. It was concluded that tribal, non-tribal belongingness and gender, alone but not in interaction with each other create significant variance on job satisfaction of primary school teachers.
