Gender pay gap to do with 'culture'
19 August 2014 Last updated at 10:02 BST
Women bosses are still earning only three-quarters as much as their male colleagues, according to a new survey.
The National Management Salary Survey found that a substantial gender pay gap still exists for managers across all ages.
Ann Francke from the Chartered Management Institute told the BBC's Justin Rowlatt that "we need to change the culture and make it much more inclusive."
She added that there is a lot of "unconscious sexism" in the workplace and it will take a conscious effort for organisations to change this.
