The numbers are in Cargill Case Ready workers  (members of the United Food and Commercial Workers Union Local 401) have voted 100 per cent in favor of a strike.

The Calgary based plant produces counter ready meat from Cargill's beef plant at High River cutting, weighing and packaging it for retail.

Key issues in the negotiations focus around income security, overtime and a lack of guaranteed hours.

The union - UFCW Local 401 - has applied to the Provincial Government for secondary picketing at every Wal-Mart, Sobeys and Loblaws location in Alberta.

They say the purpose of secondary picketing is to make the case to Cargill’s customers that they should not purchase Cargill products until the company gives its workers a fair deal.

Union President Thomas Hesse says members are being asked to register for picketing shifts at the plant and secondary picketing at retail locations like Wal-Mart, Safeway and Superstore.

In a letter to members on the Union's website they note that impacting Cargill's customers is going to be a key part of their strategy.

Executive Director for UFCW Local 401 Chris O’Halloran says secondary picketing at the retail stores will be the action that will put the most pressure on Cargill to give workers a fair contract offer that addresses their needs.
