The contract dispute between Teamsters Local Union 174Teamsters Local Union 174 and Waste Management continues with no resolution in sight.

The union represents garbage truck drivers working for the Houston, Texas-based Waste Management.

The contract between the union and Waste Management expired March 31, but the drivers have continued to pick up garbage, recycling and yard waste on schedule.

The truck drivers serve King and Snohomish counties including Maple Valley, Covington, Black Diamond and the surrounding area.

According to Michael Gonzales, spokesman for Local 174 the two sides have not met at the negotiating table since April 6.

Waste Management negotiators presented the union with its last offer April 1 according to Jackie Lang, spokeswoman for Waste Management.

The union returned with a counter offer April 2.

Gonzales said the union has filed an unfair labor practice complaint with the National Labor Relations Board against Waste Management.

“Right now we are waiting for them to come back to the table,” Gonzales said.

The union entered into a settlement agreement March 31 with Allied Waste Service, which is owned by Republic Services with corporate headquarters in Phoenix, Ariz. The contract has not been ratified by the members.
