"Despite the BBC's public insistence that my appointment demonstrated its commitment to gender equality, and despite my own insistence that equality was a condition of taking up the post, my managers had yet again judged that women's work was worth much less than men's", she added in the letter. Currently, the pay difference in the United Kingdom stands at 18.1% for all workers or 9.4% for full-time staff.
The pay row began in the middle of 2017 when the BBC published a list of its top-earning stars, which revealed that only a third were women and the top seven were all men.
Across the pond, similar movements are afoot. She was, until her resignation, the British broadcaster's China editor. I no longer trust our management to give an honest answer. "I miss Catt Sadler".
She said: "I didn't feel that it was a solution, I felt it was a divide-and-rule, botched solution that would not make the BBC better".
"And in July 2017 I discovered the enormous gap that the two men - who were worldwide editors - were earning 50% more at least than the two women who were global editors".
These results will be made public on a new government database that aims to work towards fighting workplace discrimination.
New laws forcing companies with more than 250 workers to publish pay bands and earnings by gender went into effect in Britain in April. This ultimately led to Gracie leaving her job as China Editor and going back to her former post in the TV newsroom where she expects to be paid equally.
But it also comes under no surprise to see large discrepancies in the financial and banking sectors, commonly known as a male-oriented environment. It has been revealed Gary Lineker is on around 10 times more than Balding.More news: Razer Phone converts to laptop in Project Linda product concept
Journalist Carrie Gracie said she turned down a £45,000 pay rise and resigned because she refused "to collude knowingly in what I consider to be unlawful discrimination" at the corporation.
"During that time the gender pay gap has reduced, but it has not reduced enough". Her letter to licence fee payers makes it clear what a hard decision it has been to speak out about what she calls a crisis of trust at the BBC, but why it is vital that the British public are clear about why she has been forced to resign her post as China Editor and return early to London.
The pay gap between men and women has been a constant battle feminists have been facing for a while now. In the case of the USA men's and women's national soccer teams, more consumers are paying to support the men's team than the women's team, even though the women are more successful. And as the New York Times reported, the gap is larger among college graduates, and "far larger in business, finance and legal careers than in science and technology jobs". It excluded the women with the biggest pay gaps.
Up to two hundred BBC women have made pay complaints only to be told repeatedly there is no pay discrimination at the BBC.
All organisations have to report their gender pay gap by the end of March 2018.
Many have since sought pay equality through internal negotiation but managers still deny there is a problem.
With top law firms now advising women who work at a senior level within organisations, it might be possible that the first wave of discriminative legal action is seen before the April deadline.
But in the meantime, we'll have to rely on strong women like Carrie Gracie to keep the spotlight on the issue.
