This article explores menstruation in the workplace in the context of a humanistic management approach which highlights the values of respect, dignity, and wellbeing at work. Increased public conversation on menstruation in recent years, supported by research showing the detrimental effects of menstrual stigma on women's physical and mental health, point to a shift in consideration for women's menstrual wellbeing. This paper is based on my research on the development and implementation of a 'period policy' at Coexist, a social enterprise in Bristol, UK, which I undertook between October 2016 and December 2017. The policy was co-designed by management and staff, and uses flexible working arrangements and contingency planning to allow women greater support when menstruating. I discuss the effects of the policy and suggest avenues for future research. [ABSTRACT FROM AUTHOR]
