Kathleen Parker [“Declare a mommy truce,” op-ed, March 6] said with remarkable resignation that “except for the best-educated and the wealthiest, it isn’t possible to reach the top of the corporate ladder and take care of babies.”

And why not? Because companies fail to acknowledge that more than half of their workforce (women and men) directly take care of children and elderly parents and have to cycle in and out of their careers.

These workers can’t keep the pedal to the metal constantly. Yet corporations continue with 1950s-style reviews and promotions. People aren’t allowed to ramp out and ramp back in without losing career momentum. They must start over, again and again, even when they have highly valued skills.
