Pros
The opportunity to have a positive impact on millions of patients throughout the country; the investment being made in electronic medical records; the investment in community service; the tradition of humanitarian policies; the broad scope of positions and opportunities across many markets; the stability of the healthcare industry, even in recessionary markets; the business model is the most efficient in the United States for delivering the highest quality care at the most competitive price with some of the best patient safety and morbidy rates in the industry; leadership has big plans for expanding the business to new markets and eventually to other nations; health care ministers from numerous countries, including the UK, visit Kaiser Permanente for training on how to more effectively deliver care.
Cons
The performance standards are aggressive, but fair; most positions are exempt salaried positions, so many people work 45-50 hours per week to ensure performance bonuses are awarded; some persons are overwhelmed by the complexity and the political nature of the organization (but I've seen worse).
