CenturyLink‘s union workers represented by the Communications Workers of America decided not to strike over the weekend after their labor contract expired.

The Communications Workers of America’s contract with CenturyLink expired at 10:59 p.m. Saturday. The union represents about 1,000 Iowa employees of CenturyLink, the communications companies formerly known in Iowa as Qwest and U.S. West.

CWA spokesman Al Kobler said union members at CenturyLink are continuing to work under a day-to-day extension of their existing labor contract. He said negotiations between CenturyLink and the union will continue while workers remain on the job.

Negotiations continued Tuesday between CenturyLink and the Communications Workers of America with the current contract set to expire at midnight Saturday.

The union represents about 1,000 CenturyLink employees in Iowa, some of whom were former employees of Qwest.

Al Kogler, a spokesman for CWA Region 7, said union members approved a “right to strike” vote in a ballot counted Monday, but that doesn’t mean a strike is imminent.

“We’re optimistic as the clock ticks we’ll get something done by the deadline,” Kogler said. “The negotiators worked through the weekend.”
