Although it is arguably a prestigious position to be Managing Partner of a law firm (depending on the firm, of course), many Managing Partners are reluctant to relinquish their practice that they have spend years building for what might be a temporary venture.
Ed Weseman suggests five ways in which law firms can help MP candidates make a dual role work. These include scoping the role and managing the practice and the MP role effectively. The one that caught my eye, however, is that MPs should use C-suite officers. It seems strange to me that law firms would employ professional managers and then try to manage the firm themselves. But this is often the rule rather than the exception.
