What are some challenges and stressors that may cause physical or mental fatigue and burnout for a nurse with a disability while working in a demanding healthcare setting?

I think you already know the answer to this but are seeking validation. Poor management, heavy work loads, poor staffing, bullies on staff who are not controlled by unit management, high patient acurity, poor existing unit morale, lack of support for staff (by administration, or colleagues themselves or both) are some of the most important things that would case buirnout.
