Most contracts provide that all the income from any professional activities, including lectures, writings, expert testimony, chart reviews, etc. belong to the practice. If there is some activity you wish to except from this broad statement, be sure to raise it and have that included in the contract. Also, if you will be allowed to moonlight, make sure that is specified. Although they may be difficult to enforce, almost all employment contracts include a restrictive covenant and a non-solicitation clause. In most states, restrictive covenants may be enforceable only if they are reasonable in terms of time and geographical restrictions and necessary to protect the patient-base of the employer.
Most covenants apply for one or two years after termination.
The geographic area varies depending on the location. A metropolitan area may have a restricted area of only a few miles, while a rural area may use 30 miles. Instead of using a radius from the practice site, sometimes townships may be listed or a map may be used. In addition to the restriction itself, the contract will usually set forth the remedy for violation thereof. These include an injunction, actual damages and liquidated damages.
