Mr. Mojica confirmed in an email that he had been fired and said that he was “deeply disappointed by this outcome.”
Vice, which is based in Brooklyn, began in Canada 23 years ago as a free punk magazine and retained much of its brazen attitude as it evolved into a corporate behemoth with a presence in film production, publishing, music, cable television and more.
The company has recently faced questions about its corporate culture. An article by The Daily Beast last month cited complaints from various Vice employees about pervasive sexual harassment in the workplace that were said to be largely ignored by management.
Phoebe Barghouty, a former associate producer at Vice, told The Daily Beast that she repeatedly experienced sexually inappropriate behavior from a Vice bureau chief who is no longer with the company. She said that Mr. Mojica, then editor in chief of ViceNews.com, brushed off her concerns.
Vice later put Mr. Mojica on leave.
Mr. Mojica said on Friday that, far from being indifferent to his employee’s discomfort, he “immediately elevated the concerns to H.R. upon being made aware of them.”
“You’ll never hear me suggest I was a perfect editor in chief during my time in that role, but in the situation in question I had done the right thing,” he said, adding, “I do not believe — and never suggested — that such behavior should be tolerated.”
Ms. Tohyama, who helped lead the National Basketball Association’s human resources team for several years, wrote on Thursday that Vice had a “zero tolerance policy” toward inappropriate behavior. “In light of the need for speed and efficiency,” she added, the company turned to outside investigators to look into the complaints.
Vice is the latest media organization to terminate employees over allegations of harassment. In the weeks since accusations of sexual assault against the entertainment magnate Harvey Weinstein were made public, similar complaints have caused prominent media figures such as the political journalist Mark Halperin, Matt Lauer of NBC’s “Today” show, the CBS and PBS anchor Charlie Rose and others to lose their jobs.
Vice said in a memo accompanying Ms. Tohyama’s that, as the company evolved, its “workplace culture has fallen short.” The company pledged to seek pay parity for its male and female employees by the end of 2018 and said that it had started sensitivity training, updated the reporting process for inappropriate behavior and reshuffled and diversified its board.
Soon after the Daily Beast report was published, Vice announced an advisory board to review corporate policies. Members include Gloria Steinem, whose “Woman” documentary series for Vice was nominated for an Emmy last year; Tina Tchen, who was Michelle Obama’s chief of staff; and Maya Harris, a senior policy adviser for Hillary Clinton’s presidential campaign.
