Newspaper Unions Make Back-to-Work Offer: The six unions that have been on strike against the Detroit News and the Detroit Free Press for three months offered to return to work under certain conditions. The newspapers responded coolly. About 2,500 workers walked off their jobs July 13, largely over work rules and wages. Talks have been held sporadically with no progress reported. The unions said they would send their members back to work if the newspapers agree to a month of intensive bargaining, give the employees their old jobs back and let them work under the terms of their expired contracts. Susie Ellwood, a spokeswoman for Detroit Newspapers, the agency that produces and distributes the newspapers, said the offer will be reviewed.
