Oh I misunderstood your question, I’m sorry. I don’t think there is hazard pay. But you should be able to take shifts at other stores to earn more. There is the 30-day catastrophe pay which allows you to be paid for every shift you are scheduled while choosing to self-isolate. I don’t think there is extra pay, however. Another option would be to use your vacation pay on top of cat pay if you take time off.
I would still contact your SM to ask them. I’m in Canada so it might be different.
