The Stop Child Labor Act strengthens enforcement of federal child labor laws by significantly increasing penalties for violations. For employers, the bill raises civil penalties to between $5,000 and $132,270 for first violations (up from $11,000) and $25,000 to $601,150 for repeat violations (up from $50,000), with these amounts automatically adjusted annually for inflation. The legislation also allows private lawsuits against employers for compensatory and punitive damages of up to $250,000 per affected child, and creates criminal penalties of up to $50,000 and one year imprisonment for willful violations. To help employers comply, the bill establishes a grant program for nonprofits, labor unions, and employer associations to provide training and compliance systems, and creates a 12-member National Advisory Committee on Child Labor to advise federal agencies on enforcement strategies. The law takes effect immediately and authorizes $3 million in funding for the advisory committee in fiscal year 2027.
