Maybe not. In my state it's the exact OPPOSITE.
In my state, employers are generally protected against additional claims by any worker who collects on a worker's compensation claim. Trial lawyers don't fare well in this type of case for this very reason. That's why the lawyers who advertise their services to people who have been denied their WCI claims are generally the same low-rent mutants who offer divorces for $499. These losers aren't even good enough to be ambulance-chasing personal injury lawyers.
I'd have to look at California's lose more closely, but it may very well be that Newsom's edict does more to PROTECT employers than anything else.
Sometimes, a comp claim is preferable to a PI claim, but this just created a bunch of claims that are presumed to be valid that would not otherwise have existed. I can’t see this being good for employers. Everyone who contracted the virus and has missed work now has a comp claim if I’m reading it correctly. WC insurers need to brace for incoming.
