While packing a vessel, a stevedore will employ dunnage, which are pieces of wood set down to keep the cargo out of any water that might be lying in the hold or are placed as shims between cargo crates to keep them from shifting during a voyage.
Because they work outdoors in all types of weather, these workers adopted a type of CAP that has a snug fit, is warm, and is easily put away in a pocket. These are a type of Beanie or watch cap called variously stevedore's cap or stevedore's hat.
Today a commercial stevedoring company is one that is involved in shipping logistics between sea and land transport.
Famous ex-stevedores include Comedian Artie Lange (although he refers to himself as an ex-longshoreman).
Two unions within the AFL-CIO represent longshoremen in the United States: the International Longshoremen's Association, which represents longshoremen on the east coast, on the Great Lakes and connected waterways and along the Gulf of Mexico, and the International Longshore and Warehouse Union, which represents longshoremen along the west coast, in Hawai'i and Alaska, and, through an affiliate, in Canada.
In the United Kingdom, the definition of a stevedore varies from port to port. In some ports, only the highly skilled master of a loading gang is referred to as a "stevedore". The usual general term used in the UK or a man who loads or unloads ships is "docker", although technically this only refers to unskilled dock labourers who do not actually go aboard the ships.
In Australia, stevedores were historically referred to as wharf labourers and were colloquially called wharfies. The Maritime Union of Australia has coverage of these workers, and fought a substantial industrial battle in the 1998 Australian waterfront dispute to prevent the contracting out of work to non-union contractors.
