I've never understood parental leave. If I want to go on a vacation, I have to plan for that and save time to use for it. If you want to have a child, you should have to plan to save your time to take and spend with the child or be in a financial place where one parent can quit their job to stay with the child. It's not like you go to sleep one night and wake up to find a baby next to you that was delivered by a stork. My fiance and I plan to try to have a child once we're married in May but it's something we will save our time off for during the early days of its life because we are choosing to try and have a child.
If a company wants to offer this as a benefit, that's awesome, but I don't understand why governments need to create law to make it a mandatory thing. Having a child is a choice.
