General Motors, attempting to recoup after a disastrous 2005, is making a top-level change within its communications staff. Tom Kowaleski, 54, president of GM global communications, will step down March 1. PRWeek has obtained an internal memorandum written by the GM communications veteran.According to Automotive News, Steve Harris, 60, who retired in 2003, before taking a position as chief communications officer at ClearBlue, Detroit, will return to GM as head of GM communications. Kowaleski, in the memo, reflected on his past seven years with the company, "filled with an incredible array of challenges and opportunities," but said that the past four months have led him to reconsider his future. "A few experiences have made me begin to think of how I really want to spend the rest of my work life," he wrote. "Those who know me, know my passion for his business and most importantly, the cars and trucks that drive our emotions like few other consumer products can. And that's not where I have been able to spend my time." He added, "I have always believed in giving 110%... [and] I'll even admit, doing this has caused at times, some loss of overall perspective." Kowaleski, who recently told PRWeek that there would likely be cuts in comms staff at GM, could not be reached immediately for comment.
