Happy day!
The day any practicing Anesthesiologist can afford to semi-retire and enjoy life is the day we are all looking forward to. This means less call/no call, day work and preferential cases with a day or two off during the week. You can forget about Holidays and Weekends as well; or, you could get a job as an "attending" and let everyone else do all the work while you teach and supervise. Nice.
Every Group has its own set of rules. Some give you "stock" in the company worth a few hundred or several thousand dollars. Bigger Groups offer you "stock" in the billing company as well. Most have "accounts receivable" that will pay you some money for a period of time 6-12 months after you retire. The important thing is to ask your new Group how the rules work for retiring members.
In the end, a partner retiring is a beneficial thing for everyone. What you want to avoid is a Group that allows "senior" partners to remain fully vested in the company and "avoid" hospital call. Some Groups give "perks" to the senior member or founder of the Group allowing him to draw full salary but avoid "call" and late afternoon/evening work. A big Group can live with one "king" but more than one will destroy the Group morale. Regardless of income, the work and the money must be shared equally. However, Groups tolerate less work from certain members because of contractual issues (a certain MD holds a lucrative contract) or commitee meetings (B.S. if you ask me). Again, you must find out which members and how many members of any Group are receiving special treatment. Ultimately, you must decide if you can "live with the arrangement" or want to look elsewhere. The market place is such that you should NOT put up with too much Sh#@ these days.
The Group that offers you a 6 year partnership track should be avoided like the Avian Flu. Most of the MD's in these Groups had a TWO year partnership track but want you to be their Bit@# for 6 years. At the end of the track you might find all of health care has changed while you were busy making those greedy bastards rich.
A retiring partner should NOT be allowed to take advantage of existing or new members. Everything should be spelled out clearly and be fair for all parties. This means hiring a foreign Physician that can barely speak English to work for 50% partner pay while you get the other 50% is VERBOTEN.
