Phyllis Weiss Haserot responds:
It's no secret that many firms’ marketing plans are built around one central strategy: Acquire individual lawyers or even groups with substantial books of business. As a result, some law firms are looking like baseball teams full of free agents switching allegiance with ever greater frequency. But is this good for the fans, or the clients?
While large firms, like baseball teams in major media markets, may have the big bucks to pay for perceived large talent, the “let’s go buy a rainmaker” strategy may be trickier for smaller firms to pull off and absorb. (Not that large firms necessarily manage it so well either, but they are not as dependent on a few individuals.) Of course, the intention going in is not continuous mobility. However, multiple moves do occur if an effective lateral integration plan is not put in place and executed well.
If you think the solution is to bring in a good rainmaker, a seemingly attractive option, you need to ask and answer these questions:
There are many potentially sensitive issues that can arise and damage a firm’s cohesiveness when a new rainmaker is looked to for salvation. Be sure that it’s not like expecting Manny Ramirez to win the World Series by himself. (Especially since he is a quirky person and the Red Sox have lost most of their top players … but I digress.)
If they are the "right" people for your firm, will fit in and share the vision of your firm, rainmakers are a tremendous asset, no doubt. But a rainmaker that does not fit in can do more harm than good in terms of internal morale, economics and even client dissatisfaction.
I caution you to think through this decision, plan carefully and do the hard work necessary. There are no magic pills, and the rest of the lawyers in the firm still have to put out their best effort.
