Not sexist.

"Women in their forties are the biggest losers in the pay divide between male and female colleagues. Official figures show they earn an average of 20 per cent less than the men, with female managers likely to experience an even wider salary gap. Women start out earning roughly the same as men."

This will be cleverly marketed and sold to us a scandal. But the key here is the equality at the start.
Do these discrepancies exist? - Indeed they do.
As previously explained on this Blog however, I conducted an in depth study on this topic about 20 years ago in S. Yorkshire.
What clearly emerged was that these inequalities arose almost exclusively because of the interrupted career patterns of females when they have families.
An additional point today is that there is so much protective legislation for females who take maternity leave, and within most family setups it is the female who stays home when the children are poorly.
When they are in crucial management positions, clearly employers who do not have the bottomless resources of councils and government, may well decide to employ men in higher positions as they may be the safer option.
Apparent fairness? Meddling? Political correctness? Or just not thinking the consequences through?
The response will be for the left to demand UNfairness and MORE "Equality of outcome."
At some point the needs of the firm must also be taken into account. Surely.
