The BBC numbers tell a different story.
Meh, in the case of Lisa Wilkinson and Karl Stefanovic there was a big outrage and the News company made the case that it was not prepared to pay Lisa the same because in his contract Karl had more duties including various specials he had to do that Lisa did not. It was a non-issue. To her, they were paid unequally for the same job.
Because the media controls the discourse, this very reasonable explanation is lost in the spin and outrage that promote Lisa as the victim and brave woman pushing but on equal pay.
Having said that, one article DID raise an interesting point. Whilst they both needed to get make up for the set. She had to have her hair done each day and so this put an extra hour a day on her prep time. Now THAT IS something that ought to be taken into account. an hour a day 5 days a week 52 weeks a year does add up and is obviously time he does not have to concern himself with.
That all said and done these people are both earning 1 million + dollars a year so I am not going to weep too much over either of them and the 1 percenter issues they have.
