The CIPD, the professional body for HR and people development, called on organisations to create awareness, tackle the “stigma” associated with menstration and train managers to be confident, comfortable and inclusive when talking to employees about menstrual health.

Four out of five respondents who experienced symptoms said they had worked when they did not feel well enough to, and one in five took sick leave, with almost half admitting they felt embarrassed talking about it.

Lee Ann Panglea, of the CIPD, said: “While many employers in Scotland already provide free period products, there is much more that can be done to create a more empathetic and understanding working environment.

“Menstruation is a natural part of many employees’ lives, and it shouldn’t be a barrier to success or well-being.”
