Wal-Mart Stores Inc. and Best Buy Co. oppose efforts by U.S. ports to set labor rules, putting the companies at odds with lawmakers backing a so-called clean-truck program in Los Angeles and Long Beach.
Trade groups representing U.S. importers including Wal-Mart and Best Buy support the American Trucking Associations, which says the truck dispute is about labor union organizing and not clean air. The groups support laws that prevent a patchwork of rules from being adopted by each port operator.
