Female consultants face a bigger gender pay gap than women in IT, finance, retail or the public and voluntary sectors, according to a report.
The poll of more than 2,400 executives earning at least £50,000 per year in the above sectors found that men earned an average of 19% more than their female equivalents.
In the consulting trade, men earned 35% more than women. In the financial and IT sectors, male executives earned 20% more than their female peers.
In retail, the wage gap was 11%, and in public and charity organisations it was 6%, according to the poll by executive job site Experteer.
Torsten Muth, managing director of Experteer.co.uk, said: "Despite the continuous effort by equality campaigners and the government, it is frustrating to see women are still struggling to be treated equally in the workplace.
"We've seen more women feeling that they have hit the glass ceiling, and some of them end up leaving work completely. As a result, employers are losing out as they lose some of their most talented workers.
"Organisations should make more effort to change the work culture and to create a fair work environment for both men and women."
