  1. Coefficient denotes number of staff in each category who left the facility permanently in the last 12 months. Coefficients, standard errors, and p values are for the interaction between the random assignment (intervention, control 1, control 2) and study period (baseline, endline). They are obtained from pair-wise regressions—facility fixed effect models controlling for workers’ characteristics. Robust standard errors are clustered at the district level
