For the year 2007 to 2008, the gap between women's median hourly pay and men’s was 12.8 per cent. Not bad when you consider breaks for pregnancy and the fact that many more women (than men) work in the low paid retail sector. Men in general, do not take career breaks and therefore tend to occupy more senior positions than women. If Harriet Harman was to publish figures that showed a wide gap between men and women who occupy the same positions, then I would take her more seriously.
From the National Statistics:
Although median hourly pay provides a useful comparison between the earnings of men and women, it does not necessarily indicate differences in rates of pay for comparable jobs. Pay medians are affected by the different work patterns of men and women, such as the proportions in different occupations and their length of time in jobs.Enough said?
