Chwarae Teg: Modern workplaces can close gender pay gap
Women managers in Wales are effectively working for free for nearly an hour every day, a professional body claims.
The management gender pay gap stands at an average of £3,188 - or 13%.
Although this is less than the UK average of 22%, the Chartered Management Institute (CMI) said it was still "unacceptable".
The findings are in its annual salary survey of more than 72,000 professionals across the UK.
Joy Kent, chief executive of equality campaign group Chwarae Teg said workplaces need a modern outlook if the pay gap between men and women was to be bridged.
