It's their responsibility to give them a salary even if the business is closed. They should be prepared in times like this, and for sure they have an emergency fund to provide their employees. It's only a simple sacrifice for the employees who have been working for them every day.
This is wrong. The salary should just be compensated based on working days. Owners can make an advanced payment but not for every month. That's already a good move. But if ever the company didn't pay from the start, that's another story.
It's not a simple sacrifice. It's easy to say they are rich but that is just numbers. If they will sustain all worker's salaries while no business until everything back on track, that will be destruction and the end of Vegas business. If the business will end, no more employment needed, no jobs, no works once the situation back to normal. Imagine the number of workers that needed to be paid. Vegas has thousands of workers.
This kind of problem should be addressed to the government.
