Male bonuses double those of women, says study

The pay gap between men and women is exacerbated by bonus payments given to male managers which are on average double those for women, says the Chartered Management Institute (CMI).

Male managers' average extra payments were £6,442 last year compared with £3,029 for women.

The difference increased at director level, with women getting an average bonus of £36,270, while men receive £63,700.

Speaking to BBC News, the chief executive of the CMI, Ann Francke, explained the driving forces behind the gap and said equality was in a firm's interests.

"Organisations that have more diversity at the top perform better - so they getter better growth; people are happier in their jobs; and they're more ethical."
