A 'routine' personnel move at BP

Chronicle business reporter Brett Clanton (no, not this guy) writes today on a change in a key U.S. exploration and production job at BP.
James Dupree has been named senior vice president over the offshore U.S. region, replacing Neil Shaw, who held the post for two years and has taken a more senior post with the company in Houston. Dupree most recently had the unenviable task of trying to salvage BP’s partnership with Russia’s Gazprom.
BP called it a “routine personnel move,” but the company didn’t announce the change, which took place this month.
Maybe it really is routine. Large corporations regularly shuffle managers around the world to help build experience and fill various needs. But it might be a bit annoying for some workers to have a new boss every couple of years.
