ABOUT one in five working mothers have considered leaving their job due to the challenges of balancing work with childcare duties, new research suggests.

Childcare responsibilities have a disproportionate impact on women and their careers, according to a report by jobs site Totaljobs and the women’s rights charity the Fawcett Society.

A survey of 3,000 working parents indicated that one in 10 mothers have handed in their notice because of childcare duties, rising to about one in eight single mums.
