Social media users have responded to the high-heel rowGetty

Women are tweeting pictures of themselves wearing flat shoes at work in protest of sexist dress codes after a woman was sent home from her temp job after refusing to wear high heels. The UK's leading women's rights charity, Fawcett Society, set up the hashtag #FawcettFlatsFriday to encourage social media users to show support in ending double standards for women, when it comes to dressing for work.

Nicola Thorp, a 27-year-old from Hackney, was asked to wear heels by the firm Portico, which provides reception services for the finance company PricewaterhouseCoopers in London. Portico asked her to leave after Thorp refused to wear shoes with a "two-inch to four-inch heel". She set up a government petition earlier this week, which will now be considered for debate in Parliament after receiving more than 100,000 signatures.
