But once he/she has a family (or just a pregnant partner) he/she is really handcuffed to the job by that perk, no? The risk of losing that cover makes it very difficult to make sensible life choices.
Is your claim that a Facebook engineer would have trouble finding a different job with high compensation and great healthcare? That's a bold and hard to believe claim.
But answering you on the merits: it’s entirely possible, yes.
For example, what if sensible life choices include moving out of state to a place where there is less tech industry? Just changing jobs can interrupt healthcare and cause costs. And the process of switching providers is, in the experience of a friend with a family with complex healthcare needs, sometimes so kafkaesque it might not be worth the risk.
What if sensible life choices involve blowing the whistle or just being critical of the industry? Can you risk it?
