OCCUPATIONAL STRESS LEVEL AMONG CLEANLINESS WORKERS OF INDORE MUNICIPAL CORPORATION ACROSS DIFFERENT GRADES.

Abstract [English]

The Quantitative study investigates the significant difference in occupational stress among cleanliness workers of Indore Municipal Corporation across different grades. Administering a survey by opting a occupational stress index developed by Dr. A K Shrivastava and Dr. Ashok Pratap Singh specifically for this research. The Null Hypothesis (H₀1) states that There is no significant difference in occupational stress among cleanliness workers of Indore Municipal Corporation across different grades. We measured the occupational stress levels among 384 cleanliness workers of Indore Municipal Corporation during the cleanliness drive.
The assumption checks indicate that the normality assumption for Occupational Stress is violated, as evidenced by the Shapiro-Wilk test (W = 0.938, p < .001), suggesting that the data significantly deviates from a normal distribution. Additionally, Levene’s test for homogeneity of variances (F(3, 377) = 29.3, p < .001) reveals a significant violation, indicating unequal variances across groups.
The results of Welch’s One-Way ANOVA indicate a statistically significant difference in Occupational Stress among cleanliness workers across different grades, F(3, 113) = 46.9, p < .001. Given that Welch’s ANOVA is robust to violations of normality and homogeneity of variances, this result confirms that at least one group differs significantly from the others. Since the p-value is less than .05, we reject the null hypothesis, which states that there is no significant difference in occupational stress among cleanliness workers across different grades. This suggests that occupational stress levels vary significantly among the different grades of workers. To further examine which specific groups differ, a post hoc analysis such as Games-Howell should be conducted. Let me know if you need help with post hoc comparisons or further interpretation.
The Tukey post-hoc test results indicate significant differences in occupational stress among different grades of cleanliness workers. Specifically, Grade-I workers experience significantly different levels of occupational stress compared to Grades II, III, and IV (p < .001 for all comparisons). However, no significant differences are observed among Grades II, III, and IV, as their p-values are above 0.05. Since Welch’s ANOVA indicated a significant overall difference, the post-hoc results help identify where these differences exist. The significant differences between Grade-I and the other three grades suggest that occupational stress is notably higher or lower in Grade-I compared to the rest. However, the non-significant comparisons among Grades II, III, and IV imply that their stress levels are relatively similar.
Thus, the null hypothesis ("There is no significant difference in occupational stress among cleanliness workers across different grades") is partially rejected, as significant differences exist between Grade-I and other grades, but not among Grades II, III, and IV.
