Hope this won't take an ugly turn for the worse.
These things were normal in many workplaces world wide. Just because few employees got infected they didn't closed down their entire workplaces especially in essential workplaces such as hospitals, PPE manufactures and food. Only thing they did was they carried out their essential services while isolating infected patients. Transportation is also another vital sector in the pandemic era. Imagine if everybody closed their workplaces, borders and waited without doing anything how are they are going to do import and export and get things that they need including things need to control pandemic.
