Not long after Facebook CEO Mark Zuckerberg annouced that he'd be taking two months' paternity leave, the decision was made to change the policy on so-called "baby leave" - Facebook now offers four months of paternity leave across the board for all of its 11,000 employees.

Facebook's Head of HR and Recuriting Lori Goler wrote in a blog post:

"Our approach to benefits at Facebook is to support our employees and the people who matter most to them. We want to be there for our people at all stages of life, and in particular we strive to be a leading place to work for families. An important part of this is offering paid parental or 'baby' leave.

"In reviewing our parental leave policies, we have decided to make this change because it's the right thing to do for our people and their families. Studies show that when working parents take time to be with their newborns, outcomes are better for the children and families. For too long, paid baby leave has been granted only to a mother who is giving birth. We believe that fathers and mothers alike deserve the same level of support when they are starting and growing a family, regardless of how they define family."

The UK will benefit in particular: UK companies on the whole give just two weeks' paternity leave.
