Tuesday marked National Equal Pay Day, a symbolic day when women's earnings catch up to men's earnings from the previous year.
On average, the American woman earns 77 cents for every dollar earned by a man. That means every American woman in this country works for free for the first three months of every year.
"When we look at the statistics and hold a constant across profession and across degree, women still make less. So part of this is just good old discrimination," according to Dr. Hephzibah Strmic-Pa w l, an assistant sociology professor at Coastal Carolina University.
Dr. Strmic-Pawl also said something known as the "Second Shift" affects the wage differences between men and women.
The 'Second Shift' relates to women having to choose between their families and their careers.
She said women are more likely to make the sacrifice to take care of their families.
"That's time away from your career, and you're going to end up getting penalized for that," said Strmic-Pa w l.
However, there are things women are doing wrong when it comes to getting paid more.
Dr. Strmic-Pawl said women need to have higher self-worth when it comes to talking to future or current employers.
"Women are more likely to be humble about their accomplishments," said Strmic-Pa w l.
She advises women to think more like a man.
"They use stronger adjectives and verbs when they talk about their work experience that cues people into thinking you're worth something."
Women should use these stronger adjectives on their resumes when looking for a new job. Also, use them when talking to your boss about a raise.
Research figures point to women and men making the same wages by 2060. Strmic-Pa w l said this is unlikely to happen.
