Dude, you're so clueless about this. Just stop. Please.
Do you know who pays the payroll? It's not the Port Operator.. it's the Ocean Line's Association organization, the PMA (Pacific Maritime Association).
The PMA pays the ILWU. (It was the PMA that locked out the ILWU in 2002).

The principal business of the Pacific Maritime Association (PMA) is to negotiate and administer maritime labor agreements with the International Longshore and Warehouse Union (ILWU).
The membership of the PMA consists of American flag operators, foreign flag operators, and stevedore and terminal companies that operate in California, Oregon, and Washington ports.
The labor agreements the PMA negotiates on behalf of its members cover wages, employee benefits, and conditions of employment for longshoremen, marine clerks, and walking bosses and foremen.
The Association processes weekly payrolls for shoreside workers and collects assessments on man-hours, revenue tonnage, and other units of cargo to fund employee benefits plans provided for by the ILWU-PMA labor agreements.
On the East coast there is a similar arrangement with the ILA (I think) union.
