state of mind in this industry. >> while shoppers clicked 24 hours a day. then in the u.s., national labor shortage and limited work hours. port of long beach is just now experimenting with round the clock operations. >> this is a wake up call for us in this industry to realize we can't operate with the model of yesterday. >> the goal cut the wait time for truck drivers. the next link of the supply chain. moving containers out of the port. >> every day five, six hours in the harbor. >> have to wait like six hours. >> six hours? >> six or eight. >> i was in there for nine hours. >> nine hours loss, a time when he could move merchandise. >> national data show there's a truck driver shortage. the problem is even more basic than that. >> the port is backed up, we're backed up. everyone is backed up. it's just big problem.
