Robert Sarver and the Phoenix Suns have been under NBA investigation since November after ESPN published a deeply reported story “detailing allegations of racism and misogyny in a sometimes hostile and toxic workplace during Sarver's 17-year tenure as majority owner.” Now, ESPN's Baxter Holmes has obtained documents showing that a longtime Suns employee resigned from the organization last month and claimed “she became the target of bullying and retaliation by superiors after raising concerns about gender equity and misconduct within the organization.”

The woman, Melissa Fender Panagiotakopoulos, began working for the Suns in 2007 and held the position of senior premium experience manager before her resignation. She had held that title since 2014.

She sent her resignation letter on May 20 to 16 members of the ownership group, including Sarver, and challenged them to address the “toxic” workplace culture. While her letter didn't specifically single out Sarver or any other individual employee, this is just more fuel on the fire for this investigation. The Suns owner came out and denied the allegations after the initial ESPN story was published.

Panagiotakopoulos offered up a list of allegations and is hoping her resignation letter will help things change for the better in the Suns organization. Here's some of what she alleged:

She alleged that there were “inherent conflicts of interest with managers' ability to receive commissions, cherry pick deals, revise suite lease terms to line their own pockets, and operate in a different manner than the rest of the sales organization with no true consistent systems or oversight.”

She also alleged inequities and gender discrimination, writing, “Is it a coincidence that I have been the only mother in the entire sales organization for the last 15 years? Is it because certain males were being paid more in equivalent roles?”

And she alleged issues with human resources' “ability to stay relevant and exert influence over C-suites — the lack of follow-up, ability to resolve conflict or true concern for employee well being.”

She had also voiced concerns in a memo back in November not long after ESPN's initial story dropped.

The Suns put out their own statement on this new matter:

“We have been made aware of allegations by a former employee and are investigating them, consistent with our Respect in the Workplace Policy,” the Suns Legacy Partners organization said in a statement provided to ESPN. “The Phoenix Suns are committed to creating a safe, respectful, and inclusive work environment free of discrimination and harassment, and we do not tolerate retaliation for the reporting of alleged misconduct.”

It's unclear just how long this investigation into Sarver and the Suns will go. There's clearly a lot to sort through based on all of ESPN's reporting. Is there a chance Sarver is forced out? Stay tuned.
