I worked for DCI for 2.5 years and worked 4 10's. I think the hours prob depends on the clinic, if they have 2 shifts or 3 shifts, and if they're open M-Saturday, or just M, W, F. My clinic was open Monday- Saturday with 2 shifts per day, so the last patient was finished by 5pm. The latest I ever stayed was 6pm, and if I was the opening nurse, I was done by 4-4:30pm. So it prob just depending on the area manager and the specific clinic. Dialysis clinics, no matter which company, sometimes make their nurses work 14.5 hour shifts, Just depends on the clinic.
I loved worked for DCI. It is a non-profit, so although they still "count bandaids" and are very tight on budget, at least you know the profits of the company are not going to shareholders. All dialysis companies have gotten very budget oriented since the cuts were made from government reimbursement for treatments. Some of the larger, "private", companies are still cranking out major profits, but it is not going to the employees or back into the clinics. They are trying to keep their shareholders happy.
You should be treated well at DCI. You get great benefits, with lots of PTO to start. The smaller feel of the company makes you feel valued, but it's a big enough company that you won't have to worry about them going under. At least I hope!
