When the anchor Gretchen Carlson filed a bombshell lawsuit accusing the Fox News chairman Roger Ailes of sexual harassment, Fox’s corporate masters moved fast.

A major law firm was hired to investigate. Two weeks later, Mr. Ailes was gone, ousted from the network he ran for two decades. Rupert Murdoch stepped in as chairman, sending a clear message: This is a fresh start.

But the grim tales about life under Mr. Ailes keep coming. More women have come forward — the latest was a former daytime host, Andrea Tantaros — describing a culture of intimidation and misogyny, and telling of settlements they received to leave the network. Some of Mr. Ailes’s top deputies who remain in charge at Fox News have been accused of aiding his behavior. Inside the newsroom, employees are still on edge about what new stories might surface and which executives could be ensnared.

If the Murdoch family wanted to leap ahead of this scandal, it is now at risk of falling behind. Some people at Fox News are asking if meaningful change can occur inside a workplace still stocked with loyalists to Mr. Ailes. “People are waiting to see,” one staff member said.
