Although it's awful that some successful casino owners and management forget to protect and help their employees who helped them to become successful, some casino owners were able to send help and give their employees the salary they need. Perhaps they don't care about their employees' financial struggle because they have a lot of money, and they can survive the whole lockdown with that money.
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.
