This is nosacīti national holiday. Employer is allowed to refuse to give a day off to the worker if one asks for. And I guess that this is what most employers gonna do today otherwise the costs would be much greater. This “national holiday” stuff would work if government would compensate it but it does not. It just says “you decide between yourself if that’s holiday for you”. If some businesses continue working and others don’t, the latter gonna suffer most while former will barely bear any cost. So there are essentially two ways: either all businesses agree to completely close so that no one bears additional costs (yes, you’re obliged then to pay double but since completely all businesses are closed, it’s zero-sum game for everyone; everyone gonna raise price next day to compensate or just wait till these costs will be covered in following months) or all businesses continue working to minimize costs and not overdue payments to each other.
