Workers must be directly impacted by imports or by a shift in production of their firm to any country with a free trade agreement with the United States or to beneficiary countries under the Andean Trade Preference, the African Growth and Opportunity, or by certain other shifts in production. Employees of upstream suppliers are eligible if the product supplied to the primary firm consists 20% of the production or sales of the secondary workers' firm, or their employer's loss of business with the primary firm contributed significantly to the secondary workers' separation from work.
