I worked at home as a Telephonic Case Manager for UHC for 5 years and absolutely loved it. It was challenging, rewarding, and a little boring at times, but I loved it. I only left because I had a baby and wasn't planning on going back full time. If you like to be around people at work, it can feel very isolating to be at home. However, all the members on your team work from home, so you build "cyber" work relationships and feel very supported.
I will tell you even though it's "work from home", you are expected to be at your desk working and your activity and production is tracked and monitored and there are certain metrics you must meet. You will feel chained to a desk even though you are working from home. At times you won't feel like a nurse, so you have to be open to working in a "business model" and you have to be comfortable with a dual role of nurse and insurance company employee. My first job was for a national Insurance Company, so it was a perfect fit for me.
