I work full time, but prn on the side . I've worked at several SNF's, and honestly, job satisfaction depends on many factors such as facility and equipment available, camaraderie among fellow therapy staff, facility and rehab relationship, caseload mix, salary, and most importantly, the company you work for. My current SNF is the cleanest, most well-kept in the area, with a large, bright loaded gym (we also do some OP) and therapy pool, wood floors, high ceilings. The rehab team is awesome, we all get along great, and nursing staff is cooperative and fun. We see very involved, total assist people, but also short term rehab, OP, and ALF pts. Our rehab company (contracted) leaves much to be desired though, with outrageous productivity standards and no raises for the last 3 years, but I can't beat the facility's atmosphere, and I love going to work everyday.
I did the prn-only thing for a while, and it can be quite a gamble . When its good, work is plentiful, and you can make bank. When its bad and caseloads are low across the board in your region, it really sucks. I almost got into financial trouble during a period when no one in the area needed help for like, 2 months. I personally wouldn't put myself into that situation again. Our company is in several SNF's in the area, and our prn will typically float to wherever they're needed, but there are times when they don't work at all.
