Negotiations are scheduled to resume Wednesday over issues that prompted a strike by Reno-area garbage workers.
The workers walked off the job Friday after negotiations broke down between Teamsters Local 533 and Waste Management Inc. over pay, job security, health insurance and vacation benefits.
About 350 company employees have been working without a contract since April 18. Of that, about 280 are union members.
Waste Management employees from other Western states were scheduled to start working Monday in the Reno area, said company manager Greg Martinelli.
Reno workers have filled in for their counterparts in Arizona and California during strikes the last three years, he said.
"We're all one company so we try to help each other out," Martinelli said, declining to say how many replacement workers were being brought to Reno.
Teamsters leader Lou Martino said bringing in the workers would hinder negotiations.
Dozens of union members walked picket lines over the weekend.
A 1967 strike by Reno-area garbage workers lasted 12 days.
