Alternatively, non parent employees at facebook can take 3 days off to cope with stress or else need to take sick days. Otherwise they can take sick days, which probably would be frowned upon if overused.
Yes, parents have to deal with a lot more added stress during this pandemic. But, the difference between 10 weeks off (with no questions asked) and 3 days off (to "cope with mental health issues") is pretty stark. It seems like the tech companies could at least give those who do not take family leave an extra week of vacation or something.
