The applicant union filed a jurisdictional dispute complaint under section 91 of the Labour Relations Act, seeking exclusive assignment of all heavy equipment floating work, which was currently shared with the respondent union.
The Board first denied the applicant's request to introduce evidence of area practice and certain documents due to its failure to comply with the Board's Rules and Practice Note regarding timely disclosure.
On the merits, the Board considered various criteria including collective bargaining relationships, economy and efficiency, employer practice, employer preference, job loss, and delay.
While economy and efficiency slightly favoured the applicant, the employer's long-standing practice of sharing the work, its preference to maintain the negotiated status quo, potential job loss for the respondent union, and the applicant's delay in bringing the complaint weighed heavily against altering the assignment.
The complaint was dismissed.
