Independent truck drivers at the ports of Los Angeles and Long Beach are on strike against three large trucking firms that operate at the ports.
Handling almost half of all the nation's cargo, the ports of Los Angles and Long Beach are the main gateway for imports from Asia.
A lot of the shipping containers end up on these idling trucks. The short-haul truckers bring the goods from here to nearby rail yards and distribution centers for companies like Costco, Forever 21 and Skechers.
"We're in this to win," says truck driver Byron Contrerras.
