It's equal pay day.
President Obama signed a new executive order for men and women to make equal pay in the work place.
The American Association of University Women says female workers earn 77 cents for every dollar a man makes.
Women at the White House earn 88 cents.
President Obama wants to change that, banning federal contractors to deny people from discussing their pay.
A Marietta College professor disagrees, saying it not about pay, it's about supply and demand.
And the fact that women are more likely to leave for family reasons.
"High supply of women in certain jobs, that brings their salary down. We have to convince people that nowadays, male workers are as likely to interrupt their career for children or family reasons, as much as the female workers do," says Jacqueline Khorassani, economics professor.
Republicans are also arguing against closing the pay gap, saying it could hurt men and women.
The bill moves to the senate and they will vote this week.
The bill is not expected to pass.
