BUSINESS BRIEFING / MEDIA

The U.S. Bankruptcy Court trustee and three unions representing Tribune Co. workers raised objections to the Chicago media company’s plan to pay tens of millions of dollars in performance bonuses.

The filings came in response to the company’s July 22 request for authorization from the U.S. Bankruptcy Court in Delaware to pay $21 million to nearly $70 million in bonuses to more than 700 managers and other key employees.

Tribune, which owns the Los Angeles Times, the Chicago Tribune and other media properties, also sought to pay nine of its top 10 executives $3.1 million in belated 2008 bonuses. Sam Zell, the company’s chairman and chief executive, is not part of the group of 10.
