I don't know why you're being downvoted. Strong labor protections and a generous social safety net with the goal of making it so that being fired isn't the end of the world would be a huge net positive for the labor market. Guilt free firing means you can allocate labor efficiently where it's actually needed specifically because you're not dealing with people's livelihoods.

And right now our social safety net for situations like this is built into unemployment insurance, we should expand it.
