The union trying to unionize the Wal-Mart store in Weyburn, Sask. has lost a battle that took it to Canada's highest court.
On Thursday, the Supreme Court of Court of Canada decided it will not hear an appeal from the United Food and Commercial Workers, Local 1400, which lost an earlier decision before the Saskatchewan Court of Appeal.
The case goes back nine years, to April 2004, when the union applied to be certified as the bargaining agent for the employees of the Weyburn Wal-Mart.
The union was certified in December 2008, but since then, the case has been back before the Saskatchewan Labour Relations Board and the courts numerous times.
The labour laws changed and a decertification drive was launched at the store.
Last December, the Saskatchewan Court of Appeal issued a new ruling that sided with Wal-Mart, allowing decertification votes to be counted.
The union sought to take that decision to the Supreme Court, but its application to appeal was dismissed.
As is standard procedure, the high court gave no reasons for dismissing it.
Walmart, which has vigorously opposed unionization in its stores across North America, said it was pleased with the decision. In a news release, the company said it means votes in the decertification drive can now be counted.
