This ownership does not imply authority over cargo screening, nor does it imply that it controls labor.
Most of the container ports on the East Coast and Gulf are ultimately managed by USMX. USMX has one contract with the ILA dock union that covers the enter area of coverage.
The function of the Port Operator is to be the coordinator between the Shipping Lines and the Union providing the labor.
The Shipping Lines tell the Port Operator which ships are coming and the amount of containers that need to be handled and how many "gangs" of labor they need. The Port Operator tells the Union there x number of people for how ever number of gangs will be needed for any shift. The dock worker goes to the Union dispatch hall and gets his assignment.
It's not like a Port Operator (who is basically a glorified vendor) can come in an errect a garrison.
