When I was in school I always thought that two consecutive 12-hour shifts was the most I ever wanted to do because I always felt so worn out doing 12 hour shifts doing my preceptorship my senior year.
At my current job that I started in October, they have me doing three 12-hour shifts in a row, I get one night off in between, then I do three more 12-hour shifts in a row, I get a week off, and then I repeat the process all over again. I am getting worn out, burned out, and the week off isn't worth the LONG week of work. It doesn't feel safe and I get so extremely exhausted, especially on the 6th 12 hour shift. I finally talked to my manager about it and she said she would see what she can do about my schedule, but nothing has happened yet.
