Dugan was sacked only months into her job as head of the Recording Academy.
Dugan says she asked the Academy not to take action when she initially brought her complaints to their attention because "I wanted to make change from within".

The complaint also includes claims of unlawful gender discrimination, unlawful retaliation, and unequal pay.
In a statement to NPR Tuesday, the Recording Academy did not address Dugan's allegations regarding voting irregularities or any board influence over the Grammy Awards. While Dugan claims the company is defaming her, she acknowledges that the complaints made against her happened prior to her complaint to HR.
"I moved across the country, I had a great job", she said on "GMA". Again, she did not name the artist involved. And I was trying at each step to take a deep breath and say 'OK, I can make a difference. I can fix this. I am able to work with this group.
"Moreover, in an outrageous conflict of interest, the Board has selected artists who are under consideration for a nomination to sit on the committee that is voting for the category for which they have been nominated".
Her concerns detailed in the memo included voting irregularities, financial mismanagement, "exorbitant and unnecessary" legal bills, and conflicts of interest involving members of the academy's board, executive committee and outside lawyers."I hate that I am in this situation because I'd much rather be here talking about the artist and the music". "I believe the good people at the Recording Academy, for which there are so many - so many good people on the board - they deserve better". He made his exit after a series of controversial comments, in which he denied that the Academy's voting was sexist, saying instead that female artists should "step up" in hopes of being recognized.

The broader picture of this story is how Dugan claims the Grammy Awards come about. Dugan was suspended on January 17 following a misconduct complaint.
The academy said in a statement that it "immediately launched independent investigations to review both Ms. Dugan's potential misconduct and her subsequent allegations".
Attorneys for Dugan said the Academy's assertion about the timing of her allegations "is completely false".
In response to her filing, the academy said Dugan's complaints to a human resources executive in December about sexual harassment and other issues came only after she was accused of abusive behavior toward the executive assistant she inherited from Portnow. Ariana Grande, who is scheduled to perform, is also one of the artists Dugan claims was sidelined due to rigged votes.
It was announced in May 2019 that Dugan would become the first woman to head the Academy when she assumed the position August 1 of that year. "But now after 5 months of being exposed to the behavior and circumstances outlined here, I have come to suspect she is right". "The goal of the Recording Academy is to support, encourage, and advocate for those within the music community. I'm excited to get started".More news: China shuts down transport in eight cities around virus epicentre
