Of course I’m going to say No.
The argument? Moms get paid less, since they work less. Since they work less, they are subsequently less qualified in the long-term. Work in this case, was being defined as time in the office (and not results).
That presumption was just one weakness picked up by the over 120 incredibly interesting comments that the post received.
My take? Almost all the MomShifters I’ve interviewed who are professionals working in a non-hourly rate job (keep in mind that this is almost 100 women now) strongly suspected (and few had been able to confirm) that yes, they were being paid less than their male counterparts. But all said that there was little they could actually do about it.
The problem? How salaries are arrived at is subjective and that’s where and why perception matters so much. As one comment pointed out, the perception is that working mothers are less productive (whereas for fathers, its the opposite). And the penalty for that belief is reflected in the paycheck.
