While at unversity, I worked at a hospital in the pharmacy, often covering the 3rd shift (11pm to 7am). There were a number of employees who had worked 3rd shift for decades and as a running joke, they kept a bulletin board with every single study that showed the negative health impacts of night shifts -- literally dozens of scholarly articles about what they were doing to themselves. The hospital maintained a decent premium (~15% IIRC) for night shift hours, but it was clear to the employees that they were making a tradeoff on their health to work at night. It's a tough problem since sick people don't wait for regular hours to crash or require care, so someone needs to be there. Maybe better coverage from split shifts?
