 where I would just come to the hospital and admit patients as they came and how a supervising physician if I would just talk about my plan since I wasn't officially a licensed board certified physician like I am now. But on the flip side, sometimes the hospitals say, hey, we actually don't need any help with admitting patients for the emergency room. We just need somebody to help cross cover all the patients when all the doctors are gone for the day. So you can imagine if you have 10 doctors in a day time taking care of everybody, there needs to be somebody there at nighttime to be able to take care of any emergencies or be able to answer questions for nurses. And so they may say, hey, here are a list of 30 patients. If the nurses call you about these 30 patients, then you have to be able to help whether it's take care of an emergency, answer basic questions from their chart, whatever it may be. But otherwise, that's all you're there for. If you're not called for anything, you just kind of hang out. So that's called cross cover. So we've talked about moonlighting and mission shifts. We've talked about moonlighting cross cover shifts. And sometimes you have shifts that are a little bit of a combination. You may cross cover some patients as well as admit some patients, but those are very typical examples back when I was a resident of things that I did, especially during the COVID pandemic where the necessity for residents and trainees to take these shifts was really hot.
