Two weeks after the Chronicle announced it was eliminating one-quarter of its newsroom, Managing Editor Robert Rosenthal (pictured) has resigned. In a note to the staff Tuesday, he said he was leaving “without rancor or acrimony,” according to a story in the Chron. His departure, he said, would give Editor Phil Bronstein room to restructure the Chronicle’s newsroom and take a “more hands-on approach” to running the paper. A replacement hasn’t been named. Rosenthal, known as Rosey, had been at the paper since 2002 after 22 years at the Philadelphia Inquirer. Rosenthal said he had not yet decided what he will do next.
