Also not updating the RTO portal won't cause any penalty from what I've heard, and ppl can update the WFH status anytime, e.g. marking their whole month as natural disaster WFH in advance if they really care, which no one really does
They don’t. They care about having legal cause to terminate employment, as is the style at the time
I was using “I think” as a conversational affordance to give OP a less confrontational way in to disagreeing with me, if even in an at-will state, termination for cause is better for the employer for some reason (I couldn’t find one when searching, but it’s not an area I am knowledge about).
I don't know the exact laws, but given California I would not be surprised if there's a "no, you cannot fire someone who's in the hospital over a state of emergency" clause. Similar to how you can't fire an employee to avoid workman's comp.
Or worse, it's not there and they set precedent.
