There is an article in today's Times (2 March) by Mary Ann Sieghert, in which (apart from some bizarre, shallow views on Cuba) she says that when Peter Stothart became Editor he did a "salary audit". He found out that many women were being paid less than men for equivalent jobs, and, eventually, ironed out the differences. M-A does not say whether he raised the women's salaries or lowered the men's, but good on Stothart either way.
Well, good for him, I say. Same work, same pay. No exceptions.
