In the memos, both sent this week, Kilar and Sarnoff address what the former calls "public reports regarding patterns of unacceptable behavior." The memos follow three BuzzFeed News reports centering on "toxic" work environments at Ellen and TMZ on TV and in anticipation of The Hollywood Reporter publishing a feature-length investigation into the workplace culture at those two shows and other Telepictures productions. (A WarnerMedia spokesperson points out the memos were meant to address HR problems throughout the company.).

In his memo, Kilar writes that he is both "concerned and disappointed in" recent stories about the company and adds, "this email is to share what we will be doing about it." The newly installed WarnerMedia leader — Kilar was named CEO on April 1 after a successful run at Hulu as its founding CEO — adds that the company has hired a "third party" to review its production business, will be recirculating its Standards of Business Conduct internally and with current and upcoming business partners, and is encouraging employees to report unacceptable conduct.

"I anticipate that there will be situations where we choose to terminate business relationships," he writes.

"I also anticipate that there will be situations where a person may choose not to work with us because of these rigid expectations.

While there may be companies that will do business with those people, we do not need to be one of them.".

Sarnoff adds that she will additionally hold "accountable" a new leadership team she's been putting in place that will oversee the tone and culture of the company.

She continues, "I’ve also empowered, and will hold accountable, the Studios and Networks HR and Legal teams to act on any issues that are brought to them.

WarnerMedia has been addressing reports of a poor work culture at The Ellen DeGeneres Show in recent weeks, parting ways with three top producers and adding new work benefits for employees?

I anticipate that there will be situations where we choose to terminate business relationships.

I also anticipate that there will be situations where a person may choose not to work with us because of these rigid expectations.

While there may be companies that will do business with those people, we do not need to be one of them.

But I know we can and will be better so long as we are clear in our expectations and hold each other accountable to those expectations each and every day.

The Studios and Networks Group is a creative nexus for all of WarnerMedia, and our success will be based on innovation, calculated risk-taking, unbridled creativity and a clearly defined code of conduct.

Over the last few weeks, I’ve been putting together my senior leadership team and I will hold them accountable for setting the tone for how we work together across the company and how we treat each other across the table.

I’ve also empowered, and will hold accountable, the Studios and Networks HR and Legal teams to act on any issues that are brought to them.

In addition, to give us a baseline on our culture and help us better understand your experiences and the work environment, we will be asking a third-party to conduct a culture survey of our group in the next few weeks

I’m truly excited about the future of the Studios and Networks Group
