Waste Management brought in more replacement drivers Monday as a 6-day-old strike by Teamsters truck drivers interrupts recycling, yard waste and trash pickups for more than 200,000 customers in the Seattle-Everett area.

Picketers are delaying vehicles entering and leaving a Waste Management yard in south Seattle.

Company spokeswoman Robin Freedman says the replacement drivers will focus on commercial customers, such as restaurants. Garbage is piling up for most residential customers.

The strike began Wednesday with a walkout by about 150 recycling and yard waste truck drivers represented by Teamsters Local 117. Garbage truck drivers represented by Teamsters 174 won't cross the picket lines.

The union says it won't stop picketing until the company resumes talks. The company says it will resume talks when the picket lines come down.
