CUPE says it's not getting very far during bargaining for new contracts for its members in the provincial public sector.

The union represents 4,200 people, who work mainly at school and health boards, as well as the housing corporation, and not directly for government.

CUPE's provincial president Wayne Lucas said the contract talks haven't been going well.

"I have to say personally for me it's been one of the most frustrating sets of negotiations I've been involved with," he said. 

"[But] we're going in with an open mind to get a good collective agreement that's not only good for our membership, but good for the province as a whole."

Lucas said government negotiators have hindered the contract talks.

"We haven't had a whole lot of trouble with the employers. It's been pretty amicable at the table with the employers. It's when we reach the table with [the] Treasury Board that we ran into trouble," he said.

CUPE is set to go back to the bargaining table on Tuesday.

The provincial government reached a tentative agreement with its largest union, NAPE, on Sept. 17.
