At the line manager level, probably many, even most. Empathy is selected against for promotion at most corporations, so if the OP is reporting to someone who is already a senior manager or aspiring to become one, it's unlikely.

That said, even the most cold-blooded bastard is going to make an effort to keep any middling-or-better employee right now. It's too hard to find competent replacements.

IMO it depends on the employee. I have some where I'd for sure go to bat to keep them around. I have some who slack off, put in minimal hours, and do a terrible job checking their work. They're a net positive, but barely, and if they were to throw a fit like that I'd tell them to take a hike.
