Then they’d need to raise her wage too which they won’t do. She’s already well paid for her position. The more she works, the more she makes. If they raised her pay and lowered her hours so she’d get the same paycheques that would be great, but definitely wouldn’t happen. She also enjoys working. Saving people’s lives is a very fulfilling job.

12 hours aren’t bad. If I could choose 12 hours 3 days per week plus a 4 hour day instead of five 8 hour shifts I’d take that easily. Or four 10 hour days. When you’re already working 8 hours, an extra 2-4 hours isn’t bad. I used to work 12-15 hour days when they’d let me, but then they started refusing overtime so I can’t do that anymore.

I believe there's studies showing that fewer handoffs lead to better patient outcomes.

I know people who prefer 12 hours shifts. My partner is scheduled for 7-7:30 shifts. Including a half hour lunch break, that means there's a 30 minute handover window while still working 12 hours... in the end they get paid for when they are clocked in/out and not when they are scheduled.

You wouldn't do 10h shifts, you would do 8h shifts or you would have daily drift in shifts and that's horrible for workers.

As other people have written in this post, workers prefer 12 to 8 since there are less error and they get more vacation days.
