I work in a hospital as a staff pharmacist. I say it depends on the hospital. No 2 weeks of my schedule are alike. I do not have a regular schedule by any means. We self-schedule so we request what days we want to have off or what days we want to work. BTW, I work 70% days/30% seconds, 3 weekends per 12 week schedule and 2 holidays a year. Third shift works regularly 1 week on, 1 week off. Our clinical pharmacists have an 8-5 kind of job, no weekends/holidays except when on call. At the hospital across town, they rotate 2 weeks day shift, 1 week seconds and 1 week thirds.
