I am a solo OB-GYN for 12 years now and wouldn't do anything else. I've had my share of partners who do less than you expect and take more than their share. I initially joined a practice where the wife of the principal physician ran the office, billing, etc. She too, was rude to patients and staff. It was a no win situation, so I had to get out. If you are buying this practice and he is retiring, I suggest you talk candidly with him about this employee, and tell him she has to go. Have him write her a good reference letter (this will keep him from having to face her when she wants to know if he agrees with her termination.) Then give her her walking papers and move forward. You can't let your employees intimidate you. I recently fired my office manager who had been with me since my solo practice opened. Patients and employees told me for years that she was bad news, and I made the excuse that "it's just her forceful personality". She was a hard worker. So efficient that she stole over $40,000 from me (probably more)! By the way, did you get it in your contract when your partner will retire? He may change his mind and decide to hang around for a long time, making your integration difficult.
