I cant comment on NICU but most people think we sit around at night drinking coffee, eating potluck and reading. But I work in a progressive care unit which also has an isolation wing. So we are always understaffed at night and we hump constantly. Nurses fighting over how many patients they have, techs fighting that they are not taking more than 8 and you know the rest but we handle it. Next time tell who ever it is to switch to nights or try to do what you do. If they are unwilling tell them to shut up because most people in hospitals DO NOT sleep at night. We wake them up every 2-4 hours plus they are dealing with their own issues.
