The appointment of a man as the country's first "period dignity officer" sparked a furious backlash.
The appointment of Grant was described as "absurd" by critics. Ian Blackford told Sky News that a woman would have been better for the job.
Grant, a former account manager for Imperial Tobacco and a personal trainer, was the successful candidate days after legislation was introduced to allow Scots access to free period products Local council and college representatives are part of the group.
Grant will be raising awareness and engaging young people in projects related to the Period Product Act, which involves getting free period products into schools, colleges, and universities. The Scottish government provides funding for his role.
The strongest candidate was Grant, according to a spokesman for the working group. We look forward to supporting the delivery of this important work across the region by changing the culture, encouraging debate, and removing the stigma around periods.
Grant did not want to talk about his new job.
The hiring decision of the charity was a mistake according to Charlotte O' Byrne.
There are parts of the job that are gender neutral. Women have been doing this job for free for a long time and there are women out there who are better suited for the role.
Scotland putting its Period Product Act into law was a huge step for the campaign to make period dignity a fundamental human right.

"We want and need allyship between women and men, but we also want it to acknowledge that women, girls, and menstruating people are the ones who have been conditioned to just shut up and put up," she said.
