Last summer, as it wrapped up multiple settlements after the Roger Ailes sexual harassment scandal, Fox News and its parent company, 21st Century Fox, were trying hard to end the ugliest chapter in its 20-year history.

The downfall of Mr. Ailes, the former chairman and chief executive, had exposed a newsroom culture that many women there called hostile and demeaning. 21st Century Fox ordered an internal investigation and stated publicly that “behavior that disrespects women” would not be tolerated.

Nearly eight months later, the company finds itself still dealing with fallout from that crisis. In late February, 21st Century Fox reached a settlement worth more than $2.5 million with a former Fox News contributor who reported that she was sexually assaulted by an executive at company headquarters two years ago, according to people briefed on the agreement.

The contributor, Tamara N. Holder, has said that the network executive tried to force her to perform oral sex on him in February 2015 when the two were alone in his office, according to interviews with four people briefed on her account, and documents that detail her claims. Ms. Holder did not immediately report the episode to the company or the police, fearing that doing so would ruin her career, interviews and documents show.
