Even though hospitals are experiencing low patient levels, hospitals have to staff for emergencies. There may not be any urgent cases. But they staff just in case. Many got furloughed. The folks left to work have a routine of clean, check inventory, continueing education. With perhaps a kind hospital administration, they had permission to stay to get hours. Procedural areas are notoriously high stress. I do beleieve some displayed inmaturity in posting the videos, not to make light of current tragedy but to release stress. You wonder everyday if you are going home with a disease you didnt come with. You know the masks you wear doesn't stop it.
