Pros
Kaiser's benefits and salaries compare favorably to other health care organizations. Kaiser is at the forefront in the field of health informatics. There are a lot of people who are dedicated to improving quality and customer service and moving in the direction of becoming patient centered.
Cons
Treatment of laid off non-union long-term employees is pretty shabby: no efforts to retain or rehire employees who don't have a disciplinary, oh, sorry, corrective action history; no significant HR support ( Of course, given the state of the HR dept. itself, that's not surprising). Kaiser is a BIG company, and like all big organizations (corporations, unions, government), at some point most of the energy is devoted to maintaining the infrastructure and status quo and the needs of the individual (member or employee) get lost in the bureaucracy.
