Beyond Biology: Menstrual Leave and Substantive Equality – A Feminist Legal Perspective in India

There is a sentence that half the working population of India has never been able to say out loud in the office: "I am in pain because I am menstruating, and I need to rest." This paper argues that the inability to say that sentence and the law's failure to protect the right to say it is not a small inconvenience. It is a constitutional failure. Drawing on feminist legal theory and the doctrine of substantive equality, this paper makes the case that menstrual leave for working women in India is not a demand for special treatment. It is the bare minimum that a just legal system owes to half the people it governs. The paper critically examines the Supreme Court's landmark ruling in Dr. Jaya Thakur v. Government of India & Ors. (2026), which elevated menstrual health to a fundamental right under Article 21- alongside its contradictory March 2026 dismissal of Shailendra Mani Tripathi v. Secretary, Ministry of Women & Child Development, where the Court warned that mandatory menstrual leave would make women "unhireable." It examines India-specific empirical data, real case studies, the intersectional burden on Dalit and informal sector workers, India's CEDAW obligations, a comparative analysis of global policy designs, and a systematic doctrinal rebuttal of the March 2026 judgment. It proposes a draft Menstrual Health and Workplace Welfare Act and argues that law as it did with workplace sexual harassment can break the taboo around menstruation and make what is currently unsayable a matter of ordinary, protected right. The argument is simple, the evidence is overwhelming, and the case is unanswerable: India must legislate menstrual leave now.
