I think you're obfuscating a lot of the information about the job.
"A few years" is really a decade and it's not exactly 8.5 weeks of true vacation. You start with 18 vacation days and only get to 28 days after 10 years of service. The 8.5 weeks number you're referring to also includes 5 days for CME and 10 days for sick leave. Not exactly vacation.
As for the compensation, I won't argue with that number since it's certainly possible. But you're not including the number of late nights and in-house overnight calls you need to take each month to trigger the differential multiplier and get to that number. I can tell you that it is more than most private practices.
Finally with regards to the pension, it's only calculated on your base pay and it's not indexed for inflation. As with all pensions, it becomes less valuable each year. A good private practice group that has a cash balance plan is a better alternative.
For those interested, the benefits handbook is readily available online:
As I said above, it's a perfectly fine job for some, just not for me. I seriously considered Kaiser, but decided that at the end of the day, I could do better from both a personal lifestyle and financial perspective at a private practice group across the street.
