We also have some of the most generous laws for taking care of your sick child. If you fire an employee because they're taking care of a sick child all the time, boy is your business in for a world of hurt.
The unemployment rate is lowest for people in their 30s, which is the time in life when it's likely people will either be getting a child or they already have a child at home that needs to be looked after. It might have something to do with our government subsidised daycare though.
