Alternative Trade Adjustment Assistance. ATAA is a benefit for workers at least 50 years old who have obtained different, full-time employment within 26 weeks of the termination of adversely-affected employment. These workers may receive 50% of the wage differential (up to $10,000) during their 2 year eligibility period. To be eligible for the ATAA program, workers may not earn more than $50,000 per year in their new employment. Also, the firm where the workers worked must meet certain eligibility criteria.
