UNDATED (CNN) -- Target, Apple and Facebook, along with 26 other U.S. companies, have signed onto the White House's equal pay pledge.
The announcement was made Friday, which is Women's Equality Day. The pledge includes a promise by employers to conduct a yearly analysis of pay by gender, as well as review hiring and promotion processes. The pledge, announced in June during the United State of Women Summit, is the latest effort by the Obama administration to address the gender wage gap. According to U.S. Census Bureau reports, women in general earn 79 cents for every dollar men earn.
When the earnings of women and men with the same job title, education and experience at similar companies are analyzed, women are still paid less, but the gap is significantly narrower. A recent study by Glassdoor found women earned 95 cents for every dollar their male colleagues earned in those instances.
