A federal mediator is scheduled to meet Tuesday afternoon with officials from Potlatch Corp. and the union representing Lewiston sawmill and power boiler employees who voted to strike over salary and pension benefits.

The talks are a last-minute attempt for the two sides to find a resolution involving 265 employees. There has been no new offer from Potlatch since union members voted to strike Aug. 5.

If Potlatch does provide a new offer, union representatives would have to take it to its members for a vote.
