Younger women are earning more than men in the male-dominated world of engineering and technology.
According to a study for the National Training Organisation for Engineering Manufacture (EMTA), women reach senior positions earlier and net higher salaries when they get there.
Women typically earn 5 per cent more than their male colleagues in their early 20s and 8 per cent more in their early 40s.
The survey, by Remuneration Economics - covering 11,000 staff (including 649 women) - shows men earn more once they are over 45 and women have left to look after families.
EMTA chief executive Michael Sanderson welcomed the findings, as showing there was no glass ceiling in the sector.
