Being hired into a known-unstable situation needs to involve a lot more cash than a stable-for-decades one. Is the assumption you're making that there will be no other market to absorb the employees? The ones who remain available will be the ones unable to find work elsewhere.
Nice and efficient. Get the same work for more money.
Actually maybe less work for more money because the employee now knows how vital they are but at the same time knows you don't give a shit about them so why should they care more than they have to about you.
Once you fire me, I'm not coming back.
