Nicola Thorp was dismissed from her temp job at a finance company in the UK after she refused to wear high heels. Since then, her story has garnered a ton of attention online, the company who dismissed her changed its dress code policy and more than 100,000 people have signed a petition in support of changing laws that allow employers to make women wear high heels to work.
On top of signing the petition, though, people who agree that the policy is completely absurd are also tweeting pictures of their flat shoes in solidarity with Thorp.
The tweet originated with the Fawcett Society, a UK-based charity focused on women's issues and gender equality.
People have since begun tweeting pictures of their flat shoes with the hashtag #FawcettFlatsFriday. Women's Equality Party founder Catherine Mayer got in on the action, as did Labour MP Stella Creasy.
Other notable tweets came from London's Metropolitan Police cadets and the Mayor of London's environmental issues team.
And even though there's been typical online trolling and misogyny since Thorp's story started to gain attention, that hasn't held supportive men back from playing along as well.
Thorp's experience has incited a discussion about workplace discrimination and sexism, and many of the hilarious tweets from women highlight the ridiculousness of the idea that high heels make a woman more capable of being a professional:
"Just off to trustee board meeting. Will I be able to cope in flats?"
"Wearing metallic flats today. Height of unprofessionalism and think my IQ just dropped 10 points"
"Flat shoes today. Pretty worried I won't be able to do my job"
And for one lucky man, the hashtag inspired some bold new fashion choices.
Tweet on, feminists!
