I've been out for a year now, and boy is my life better! I absolutely hated working at DaVita. I still check to see what's going on occasionally because of my coworkers and I can see little to nothing has changed.
Still same bad pay and benefits, same disregard fro anything but profit, complete mistreatment of employees... I didn't really expect to see that much has changed, but it's still disheartening to see this, especially since I know so many great people who still work there.
All I can say is, there is life after DaVita. Don't let them get you down, there are much better jobs and companies out there that actually care about their employees.
