Kay Hymowitz explains this very well in her Wall Street Journal article, Why Women Make Less than Men. Basically, men work more hours than women--on average.
The Labor Department defines full-time as 35 hours a week or more, and the "or more" is far more likely to refer to male workers than to female ones. According to the department, almost 55% of workers logging more than 35 hours a week are men. In 2007, 25% of men working full-time jobs had workweeks of 41 or more hours, compared with 14% of female full-time workers. In other words, the famous gender-wage gap is to a considerable degree a gender-hours gap.
Eagle Forum's recent alert highlights how the Senate voted against discussing the so-called “Paycheck Fairness Act.”
We applaud the Senators who stood up against phony allegations of a “war on women” and voted against a Motion to Proceed to discussion of this terrible bill. Here is the roll call vote. Please contact your Senators and either thank them or hold them to task for today’s vote.
Please note that Harry Reid voted NO on this bill as a procedural maneuver to reserve himself the right to bring the bill to the floor again. Reid once again moved to pass the so-called “Paycheck Fairness Act.”
