Gender discrimination

Good point, job equivalence can be difficult to measure.
The recent row at the BBC where Carrie Gracie resigned as China Editor because she wasn’t being paid the same as the US/Canada Editor is a good example. Doubtless she could do Jon Sopel’s job with more success than he could do hers since he’s not a Mandarin speaker, but that’s not really the point.
Far more important is the value of the job, and I’d say news from the US and Canada is a good bit more worthwhile than that from China and the salary should reflect that. It should also reflect experience and take no regard as to whether the candidate has internal or external genitalia.
The BBC hasn’t appointed a replacement for Ms Gracie’s former post, China has merely been added to the Asia/Pacific Editor’s brief.
