Delta CUPE members Wednesday night voted to file for mediation in its contract negotiations with the Corporation.

"Our members met yesterday to discuss the state of bargaining and provide direction to their bargaining committee," said Darryl Robison, president of CUPE Local 454. "The members in attendance expressed frustration that there has been little progress made at the table and felt that mediation might be the solution to break the deadlock."

The two sides last met on Nov. 8, but failed to come to an agreement.

Ken Kuntz, Delta's director of parks, recreation and culture, earlier this week said that management staff would be seeking direction of council and would be prepared to get back to the bargaining table in mid-December.

"Nov. 8 was the first time we have met since late June," Robison said. "It seems that reaching an agreement is not a priority for the employer."

The union represents more than 850 civic employees. It also represents civilians at the Delta Police Department and Delta Museum and Archives employees, although those negotiations are being held separately.

Delta's unionized workforce has been without a contract since the end of 2011. Delta is negotiating directly with its employees after leaving the Metro Vancouver Labour Relations Bureau.

Robison said the union is prepared to meet on any day in November or December to reach an agreement with Delta.

"We feel that we can reach an agreement quickly if the employer is ready to sit down and discuss the outstanding issues."

Agreements were recently reached between New Westminster and CUPE Local 387, as well as Vancouver's deal with CUPE Local 15, both four-year contracts that provide 6.75 per cent wage increases.

Kuntz said the municipality is not asking for any concessions from the union and is looking at a settlement similar to what has been reached in other municipalities.
