There are many varying forms of gender discrimination in the workplace but commonly it indicates that workers or job applicants are viewed differently or unfairly due to their sex or gender. The discrimination can come up in any way such as demand for sexual favors, prejudiced in the recruiting process,  firing on the basis of gender, passed over for promotion, or unequal because of their gender.
