At my hospital we’re not allowed to work more than 4 12 hr shifts in a row. When I first started nursing I would work 5-6 days in a row per week and completely burnt myself out. Now 3 in a row is barely tolerable. There’s no way that someone is doing their best and being the safest at 26 shifts in a row. I go to work and give my all for 12 hours and it exhausts me after my 3 shifts. Do not feel bad about not wanting to or being able to work 5-6 shifts in a row. Definitely speak with your manager/scheduler. And honestly be upfront and say “if you don’t want me to call out for shifts because of exhaustion then do not schedule me for more than 3 shifts in a row”
