Pros
Being a nationally well-known hospital, having UPMC (no matter the specific facility) on your resume is a definite plus. There are numerous types of jobs available ranging from the normal '9-5' desk work to the '24-7' hands-on work with patients. Whether you are a student, fresh-out of college, looking for a career change, or just need a job ASAP, you really can't go wrong with UPMC. Specifically within WPIC, the workers are diverse (age/race) and it's a good place to get experience working with mental health patients of all kinds. Plus, the benefits and retirement package are decent.
Cons
The turnover rate is high, which is never a good sign. WPIC mandates (mandatory overtime) their workers often mostly due to the shortage of employees, and direct care workers often work understaffed on their units. Working with patients is very stressful and can be dangerous at times depending on which population you work with... the employee shortage does not help these matters at all. Loyalty and trust between co-workers/supervisors is questionable. There are no worthwhile incentives offered by management. Favoritism and general unfair treatment is seen between select supervisors and co-workers. Equipment and furniture are old and outdated, and there's often a shortage on towels and bed linen on some patient units. How that happens in a place that racks in billions in revenue (not-for-profit or not), I don't know. Oh, and parking sucks.
