We now know that not physically giving birth to a baby doesn't preclude the need to spend time with the newborn. So Richard Branson's (inset) new policy at Virgin, that will see new fathers granted 12 months fully-paid paternity leave, is welcome. In Ireland, men aren't legally entitled to any leave, but will soon be entitled to two weeks. Bar the benefits to family life, the benefit to women would be enormous. If dads were compelled to be at home, then your boss might envisage him with a baby sling and not you balancing him on your child-bearing hips. And sharing paternity leave would have the same impact on the company's bottom line as the current system. Only there'd now be a daddy track as well as mammy track.
