Docker is a term used to describe a person who works in the maritime industry. A STEVEDORE, or dockworker, is someone who loads and unloads cargo from ships at ports. A LONGSHOREMAN is a dockworker who is responsible for loading and unloading cargo from ships onto docks and other vessels. Both stevedores and longshoremen are essential to the maritime industry, as they ensure that goods are safely and efficiently transported from one place to another.
