Mass. Market: Clear Channel's labor relations still cloudy

Boston private equity firms Bain Capital and Thomas H. Lee Partners won a major victory Tuesday when Clear Channel shareholders overwhelmingly approved their $19.5 billion buyout offer. The deal seemed to be in jeopardy at times in the past year, and had to be sweetened to ensure a solid level of support.

When the acquisition of the San Antonio-based radio station and billboard operator finally closes, Bain and Thomas H. Lee will find another constituency to think about that's a little closer to home: Clear Channel's billboard workers in Massachusetts.
