Both sides claimed victory Wednesday after a Quebec arbitrator imposed a first contract at a Wal-Mart store (NYSE:WMT) in St-Hyacinthe that gives existing employees a slight wage increase to offset union dues. The two-year agreement provides 150 to 200 existing employees a 30-cent an hour wage increase in each of the next two years. Newly hired workers will not be eligible for the wage increase.

Wal-Mart Canada, with 318 stores and more than 77,000 employees, is part of the world’s biggest retailer, U.S. based Wal-Mart Stores Inc.
