Vantaggi
J2S has a lot of options for healthcare workers, even if you've got no experience, and most of their opportunities are long term jobs if you want them to be. They are also very flexible in working with employees and their availability to work. They worked around my school schedule and other jobs schedule. Now they are my main job.
Svantaggi
I worked for a few of J2S's different clients and some are more accepting of "agency" staff than others. But if you just pay attention to your own work and don't get caught up in the gossip then you'll be fine. Just remember that you're there to serve the residents and take the best care of them that you can, and the rest is just noise.
