[9] A menstrual leave policy was first applied in some job sectors in post-Revolutionary Russia at the turn of the 20th century.
[1] A girls' school in the south Indian state of Kerala had granted its students menstrual leave as early as 1912.
[10] In the 1920s, Japanese labor unions started to demand leave (seiri kyuka) for their female workers.
In 1947, a law was brought into force by the Japanese Labor Standards that allowed menstruating women to take days off work.
[2] Taking leave may require telling managers who are males about something the woman believes to be a personal issue.
Coexist, a Bristol community interest firm, introduced a "period policy" in order to give women more flexibility and a healthier work environment.
Hoping to break down the menstruation taboo, Coexist became the first company in the United Kingdom to implement this policy.
