I agree for something like a McDonalds employee or even entry level software engineer but this is a senior managerial role at Facebook. Nobody needs to do this job. Unless your spending is out of control you do not need this income. So if it comes with unreasonable demands, I don’t really care. There are problems worth caring about and this ain’t one of them.
What the leadership does will be mirrored down to the grunt. I have never lead a multi billion dollars corporation but from my view if your team can discard someone easily, they can also bear not having that person around for two weeks. Or a year.
Honestly I feel that father and mothers getting back from a years parental leave usually comes back with better focus.
