Which is why severance payments in fang are tied to not suing the company. If that works when you lay of 10% of the company why doesn't it work when you want to fire 1 individual?

You can definitely argue it's not fair to pay somebody extra for not doing a job but the alternative seems to be you keep paying them even more to keep not doing a job (and possibly doing negative work).

Rather than put somebody on a pip for x months just offer them x months of salary to quit. Same money, same work done.
