It is easier for a boss to fire his workers during this time, they can just made a reason because of the pandemic. Paying the workers, including a situational circumstance like this will depend on the contract signed by them especially if they are working with celebrity.
Bosses are firing their workers due to financial problem that they are experiencing during this pandemic, that is because they aren't allowed to operate and as they are paying their worker's wages the business have no profit to make it become stable. The reason why most of the businesses are closed it is because of the economic crisis that a country is experiencing. You can't pay your employee if they don't go to work, that's the reality of life. Celebrities are not that rich enough to pay all of those worker's salary even if they don't do their work, but they can give help or financial support amidst this pandemic.
Don't hate anyone, let us be equal here, take a look on the contracts.
But what is the sense of contracts if the business is closed? For sure if they still come after the contract then the business will soon become bankrupt.
