After Sam Zell took over the Tribune Company a year ago, layoffs and early retirements continued at the Los Angeles Times. Eddy Hartenstein, formerly with DirecTV, became publisher in August, saying that Zell had promised to give him broad discretion. In October, the paper laid off 10% of the editorial staff. Last month it lost more staff when the Washington Bureau was consolidated with other papers. On Monday, the Tribune Company declared bankruptcy. When he became publisher, Hartenstein said he didn't need the job and that if Zell reneged on his word he would quit. Will he?
