Employment discrimination among the discriminated castes and religious groups in particular are not well captured in the literature. This study measures and analyses gender discrimination in wage employment in discriminated castes and religious groups in Indian labour market. Employment discrimination is considered as dissimilarity in employment in terms of types of job contract, social security benefits, type of activity and job skill among equally endowed workers because of differences in gender, caste and religion. Probit link function is used to construct a counterfactual distribution of employment. Gender discrimination in measured by using ex-ante approach of inequality of opportunity proposed by Ferreira and Gignoux (2014). The median relative polarisation index based on relative distribution is used to compare the relative position of women workers in the employment and wage distribution. The study observes that gender discrimination presents both in employment and wages and it varies across social and religious groups.
