An inappropriate touch. An insulting dismissal. A sexual ultimatum. A suggestion that a job is not fit for a woman.

Droves of women have shared their own experiences with workplace sexual harassment on social media this week, spurred by claims against Bill O’Reilly, the Fox News host. The revelation that five women received settlements totaling $13 million after accusing him of sexual harassment or inappropriate behavior has prompted more than 20 companies to pull advertising from his show, while others have called for his dismissal.

The outpouring came six months after thousands of women posted accounts of being groped or assaulted in the wake of Donald J. Trump’s boasts on tape that he had forced himself on women. In each case, social media offered an outlet for women who said they had either been too afraid or too ashamed to describe their experiences publicly, or to report them in their workplaces for fear of retaliation.

As reports circulated about the O’Reilly case, a hashtag, #droporeilly, was born, and it soon morphed into a meeting place for women to describe the professional mistreatment they said they had endured.
