A Sydney hotel supervisor has lost his job after making a sexist and offensive comment on the Facebook page of Fairfax Media columnist Clementine Ford.

The Meriton Group confirmed that Michael Nolan was no longer employed by the company, after he labelled Ford a "slut" when she spoke out publicly against misogyny and online harassment.

Ford, a weekly columnist for Daily Life, made a number of posts on her Facebook page on White Ribbon Day, which aims to prevent men's violence against women, in which she highlighted recent examples of online harassment she had received.

Ford included screenshots of a number of abusive messages that had been sent to her, including images Ford said were a "little violent in theme", and included unsolicited images of male genitalia. In one post, a man had suggested that Ford would "jibber less with a cock in [her] mouth".
