This wasn’t necessarily based on discriminating based on a person’s gender but to do with children.

Shilpa Wymer, managing director of Holborn Training Ltd, said that women had to make a decision to either have a greater part in their children’s lives or opt for a nanny instead.

Ms Wymer said: “[Women] have to take a step back and I think that’s where the salary difference occurs.

“They can’t possibly put in the hours that maybe their male counterparts can or women who don’t want to have children or don’t mind having a nanny in place.”

According to the International Personal Banking (IPB) Quality of Life Index by NatWest 83 per cent of women say working abroad has improved their career prospects.

Holborn Training Ltd operates Pitman Training centres under franchise from Pitman Training Group. They train students to help them find their dream job.
