Massage, Ms Harman?

Harriet Harman's office has been told to stop using that ridiculous 22.9% pay gap figure

But what I wanted tp pick up on was this:

The Government's equality watchdog, the Equality and Human Rights Commission, said the ONS report was 'important' but insisted it should also have compared the pay of full-time men with part-time women - which gives a 39.9 per cent pay gap in men's favour.

Now the logic of including this escapes me - it's clearly designed to simply maximise the gap - is it fair to compare part-time jobs with full-time ones? Considering men earn even less part-time surely it reflects the gap between full and part-time, not gender?

But I thought I'd work out the alternative

Full-time men vs part-time women = 39.9% gap
Full-time women vs part-time men = 33.5% gap [in favour of women]

Surely Harriet should be using both?

Unless she just has an agenda...
