The union representing striking Coca-Cola workers in Saskatoon is asking the public to drink Pepsi until the strike is over.

Fifty-three workers are on the picket line at the city's Coke plant.

The Retail, Wholesale and Department Store Union says a crucial issue is job security. It says Coke is trying to get rid of the union delivery crews by outsourcing their jobs.

Despite the strike, Coke will still be able to move its products into Saskatoon, RWDSU spokesman Rocky Luchsinger said. So he's asking for help from local cola drinkers.

"If the consumers decided that they were going to support the workers and go with the opposition Pepsi-Cola, that would definitely help our cause," he said.

The workers already appear to have public support, Luchsinger said.

"Even though this province has taken a shift to the right, obviously they realize the blue-collar workers [are] taking a kicking," he said. "People are honking and giving us support."

Coca-Cola says it offered workers a comprehensive contract with wage increases.

Company officials would not comment on the outsourcing issue, but said its offer did include flexibility to meet its consumers' needs.
