I worked midnight to 8am as a security supervisor at a hospital. It was nice in some ways and awful in other ways. Honestly, all the ways it was awful occurred outside of the actual shift itself. It was harder to hang out with friends, I was always tired, I had to try to get tired and sleep while it was sunny out (blackout curtains and sunglasses on the drive home ftw), and the world was waking up while I was going to bed. It was hard on my relationship with my wife.

The shift itself was pretty great actually. The hospital was quieter at night. As a supervisor, I did have some issues with my guards falling asleep at desks or trying to hide and take naps. Two people got fired over it. But most of them were pretty good. One guy fell asleep while driving the patrol vehicle and crashed it into a gate. That was embarrassing for everyone and he ultimately lost his job (he didn't admit to falling asleep, but we all suspected it - he was working two jobs and was perpetually tired). The best thing about the job was sneaking up onto the roof early in the morning on my patrols and watching the sun rise.
