Pros
The only reason I can think of is that it is a home health company and if you do PRN work you can tell them when and where you will work and you may get a better per visit rate.
Cons
Very stressful workplace. There was a very heavy marketing push in the agency. New programs for therapy are marketing tools for increasing visits. Management bonuses require lots of patients and lots of visits. Therapists do the work and management gets the benefits. Continuous computer updates make it impossible to figure out what is required as far as documentation. Just when you think you finally have got it under control an new "enhancement" shows up and you are back to square one trying to learn new requirements or unlearn something you were told that was incorrect. Management is often clueless and employees are given the wrong instructions/wrong directions. The turnover is HUGE. And did I mention long long hours due to huge territories.
