Do not return list

I'm not on here often, but I figured I'd get down to something that's been bothering me. I've been DNR'd from 3 facilities unfortunately. Actually 4. I was wondering if it's like a permanent thing with the agency you work with. It's been almost a year since I've been put on their DNR list, would it still affect me if I tried to get a job at that facility? Or is it kind of like "You can never come back here again even if you put time into another facility"? I work full time at one facility I recently started with and would like to put some time in. The longest time of employment in the 10 years I've worked jobs between non-healthcare related and healthcare related is 2 years to 2.5 years. I was young, still am depending on who you ask, and I was constantly burned out with everything. I'm trying to build impressive resume with work history ranging from 5 years to 10 years. Is DNR permanent regardless of agency or only an agency thing?
