There are various types of family leave available to fathers across and within countries. The specific design features of family leave policies are associated with how well used they are by fathers, and the key features associated with higher take up by fathers are presented here. There is an emerging literature on the various impacts of fathers on leave in relation to factors such as family health and well-being and gender equality in the labour market. In particular, fathers and family leave are important for a good quality of infant life. Finally, the chapter considers ways in which employers can support fathers in the workplace to take leave, in light of the range of associated benefits.
