In the summer of 2000, Mr. Elkington was preparing to negotiate with CLAC about a “project agreement” to cover its next construction site at the Weyerhauser site in Grande Prairie and he approached Mr. Ross for advice. The then current collective agreement with CLAC was not due to expire until December 31, 2001. He wanted to discuss how to set up an agreement for the project that would be a valid collective agreement and would withstand challenges and harassment from other unions.
The Employer argues that it and CLAC shared a common interest against a common foe and in reaching an agreement that would withstand the threat of challenges or harassment by other trade unions outside their bargaining relationship. Once they reach a collective agreement, CLAC argues, the Employer and CLAC stand beside each other to vigorously defend the fruits of their efforts against a common foe, being anyone who would attack their agreement.
