After receiving a TAA petition, TAA investigators analyze the facts to determine whether increased imports or shifts in production or services contributed importantly to the workers' actual or threatened layoffs or work reductions and to determine whether the required minimum proportion of the workforce has either been laid off or is threatened with layoffs. Information is collected from the firm through the Business Data Request form.
Expeditiously completing this form is necessary for the U.S. Department of Labor to determine whether these workers may be eligible for federal benefits. By law, this determination must be made within a certain time period following the filing date of the petition (19 U.S.C. 2273(a)).
