The Massachusetts Senate recently followed the lead of the House of Representatives by passing a comprehensive bill to regulate noncompetition agreements. While this seems to be progress toward a final re-writing of laws that govern these often troublesome employment agreements, the Senate version of the bill varies significantly from the one unanimously passed last month by the House. That means, of course, that the two legislative bodies must huddle together and work out their differences. If they can do so and garner approvals of any agreed form in both the Senate and House, a noncompetition bill would be presented to the Governor for his signature. Because the current session ends July 31, the Senate and House need to move quickly.
