I think they have fundamentally misunderstood the impact of childbirth on the human body, and the physical and psychological risk involved to some women of rushing back to jobs where they may not have a lot of autonomy and may be required to do pretty physical or demanding work (it is much easier if you are the boss or run your own enterprise/projects and get more of a say in how you plan your time and effort). It also underestimates the sheer effort involved in caring for the very young, and the lack of sleep.
It's actually pretty insulting and devalues the contribution to the human species made by people who are procreating on behalf of everyone else. And makes babies look like a designer lifestyle accessory rather than accepting this is about as fundamental to the human condition as you can get.
Much better to make arrangements for everyone to be able to have sabbaticals, if we can afford that as a nation, and this incidentally should include people who have given birth otherwise they will be deprived of reflection and personal development time simply on the grounds that they gave birth - pretty sexist when you think about it.
