Tribune trimming beyond newsroom

The Chicago Tribune will trim non-newsroom staff next month as it struggles to cope with unprecedented declines in revenue, interim Publisher Bob Gremillion said. "We've already announced newsroom staff reductions, but our dire economic situation requires us to implement further cuts elsewhere in the company," Gremillion told staffers Friday. "We've not yet determined the total scope of the reductions, but they will be involuntary." Cuts will be made by the end of August. The cuts come as all Tribune newspapers reduce their payrolls and shrink editorial output to deal with a drop in revenue that accelerated just as CEO Sam Zell took over the company in December, shouldering it with $8 billion in new debt in a leveraged buyout.
