The unexplained one-day restrictions, apparently resulting from ICTSI's latest feud with the International Longshore and Warehouse Union, put companies such as Mitchell Bros. Truck Line Inc. in a bind. Mitchell Bros., of Vancouver, usually picks up and delivers about 350 containers a day at Terminal 6. The sudden restrictions, a day after a holiday when T-6 had been closed to trucks already, left the company holding numerous containers in its yard, disrupting pickup and delivery schedules for customers. "We had $20,000 to $30,000 in lost business," some of which the company will make up later, general manager Dave Braman said Tuesday. "Tomorrow will be even worse, because it'll be busy with everyone trying to get back into the Port. It's very frustrating, and it's lost wages for drivers because they weren't able to work full days."
