Men are earning double what women earn in bonuses, according to a controversial new study that indicates the gender pay gap is as wide as ever.
The Chartered Management Institute (CMI) found that male managers earned average bonuses twice as big as those of their female counterparts over the last 12 months - £6,442 compared to £3,029.
Using data from the National Management Salary Survey (which includes data from more than 43,000 UK workers), the CMI found that men stand to earn over £141,500 more in bonuses than women doing the same role over the course of a working lifetime.
The gender bonus pay gap is starker at more senior levels. Female directors earned an average bonus of £36,270 in 2012, but this was dwarfed by the average bonus men picked up - £63,700.
The study also found that, at managerial level, men are more likely than women to get a bonus (42.3% compared to 40.6%), but this gap is biggest at director level, with 42% of female directors taking home a bonus in the last year, compared to 52% of men.
Similarly, while male managers' earnings across all levels are rising faster than women's for the first time in five years (3.2% compared to 2.8% including bonuses), male directors' earnings rose 5.3% over the last 12 months, compared to just 1.1% for female directors.
Ann Francke, CMI chief executive, said: "Despite genuine efforts to get more women onto boards, it's disappointing to find that not only has progress stalled, but women are also losing ground at senior levels.
"Women are the majority of the workforce at entry level but still lose out on top positions and top pay. The time has come to tackle this situation more systemically."
Mark Crail of salary specialist XpertHR added: "There is no good reason for men to still be earning more in bonuses than women when they are in very similar jobs. But it's often the case that men and women have different career paths, with ‘male' roles more likely to attract bonuses.
"While women are generally getting lower bonuses than men, especially at senior levels, they may be entering occupations where there is less of a culture of bonus payments. The question for employers is why that's the case."
