Two passages jumped out at me:
"It also referred to a study which suggested there was a "long-term scarring effect" on the future earnings of women who initially take on part-time responsibilities when they return to work after maternity leave."
"While mothers working full-time were on average found to have suffered a "wage penalty" compared with their childless female colleagues, older mothers were said to be paid 12% more. This was said to be because woman who gave birth when they were over 33 often had already developed their skills and were more likely to return to full-time work soon after maternity leave."
Is there an underlying point here in terms of, when deciding whether and how long at stay at home after a baby is born, and which parent does it, there is more than current cash flow to consider?
