Trade

Trades are industries that rely as much on artistry as much as scientific knowledge. These workers are trained more in the methods and standards of their industries rather than broad theories and facts. A cultural myth of inferiority persists about these jobs simply because they don’t require a university education, however, tradespeople provide the support that is required for other professionals to do their jobs effectively, and the global economy would not function without them. These professions are licensed and regulated.

Artisans, in various industries

These tradespeople make goods for use in further manufacturing industries or directly by consumers
EG: Tool makers and jewelers

Assistants, in various industries

These tradespeople provide teamwork and support to professionals
EG: paramedics and legal secretaries
