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.
While I agree that businesses should be socially responsible and if they can they should support their employees which have been part of the reason for their success, at the same time we cannot put all the responsibility on the shoulders of those businesses, I have a lot of friends that are suffering in this crisis and they lost their jobs but even if they earned a good amount of money over the years they have no savings they could use to sustain themselves despite the fact that is basic knowledge that you should have a few months worth of savings in the case you lose your job, as such people that have no savings are also responsible for the difficult situation they are in and should shoulder the responsibility as well.
