When I worked in HR at a call centre, we faced a significant issue with some female call handlers frequently calling in sick once a month due to "women's issues". While we had numerous policies to assist parents in caring for their sick children, we lacked policies allowing flexible working for women suffering from endometriosis, severe period pains, and other related conditions.
Given the nature of the job, working from home wasn't an option. Therefore, we introduced "flow days". If a woman had been absent due to endometriosis, a heavy menstrual cycle, or excessive period pains, we would offer them "flow days" going forward (our term for what was essentially a shift swap). This meant that if they called in sick with the same issue, their manager would give them the option of taking it as unpaid sick leave or working the time back on an agreed date to suit the business needs. These absence dates were monitored to ensure the women weren't using the option dishonestly.
Over the following 12 months, the company saw an 88% reduction in sick days due to women's health issues. This meant the business paid out less overtime to cover the days these women worked to "pay back" their missed hours. They would work back their hours by covering overtime shifts caused by other advisors' annual leave or projected busier business days.
During appraisals, the staff who used the service were extremely positive about it. They appreciated that their employer wasn't penalizing them for their condition and that they weren't left with a reduced pay packet for what was essentially an ongoing health issue.
This flexible working policy significantly boosted morale and improved staff retention as well. I left the company a year after the policy became active, but they continued using it.
