With a weekend deadline fast approaching, the two sides in the Minnesota Orchestra dispute are talking intensely and confidentially.
But if there is progress, it has not been visible.
Meanwhile, sources say private efforts are underway to raise money that might help bring a contract settlement before Sept. 30. That is when Music Director Osmo Vänskä has said he needs the musicians rehearsing in order to prepare for Carnegie Hall concerts in early November.
Other sources have speculated about whether the state of Minnesota could find money to help reach a deal.
The orchestra's board issued a statement Tuesday saying an offer given on Sept. 14 had expired Monday without a response from musicians.
A spokesman for the musicians would say only that both sides are still talking through mediator George Mitchell, a former U.S. Senate majority leader.
Details of the proposal that expired Monday were not released because they are part of the confidential process with Mitchell.
"Despite this current setback, the board remains optimistic," said Richard Davis, chair of the negotiating team. "We expect to continue dialogue and use every day in the week ahead to seek a settlement."
