The Spanish government Thursday granted final approval to a law creating paid menstrual leave for workers, making it the first European country to pass such legislation.

The bill modifies Organic Law 2/2010 on sexual and reproductive health and the voluntary interruption of pregnancy. It was approved following a final debate in the plenary session of the Congress of Deputies. The law passed with 185 votes in favour, 154 against, and 3 abstentions.

The legislation permits workers experiencing severe menstrual pain to take off as much time as they want, with sick leave paid for by the state social security system rather than by employers. Leave will require a doctor’s approval. The bill is part of a broader law which includes provisions aimed at facilitating access to abortion in public hospitals and mandates that menstrual products be distributed for free in schools and prisons.

Menstrual leave is currently only offered in a handful of countries around the globe, including Japan, South Korea, Indonesia and Zambia. Spanish Equalities Minister Irene Montero called Thursday a “historic day” of progress for feminist rights.
