Decisions to Newest file fiscal year 2026, quarter 3Read from the committed copy
Employer-specific case information that appears on this website was provided to OFLC by employers who submitted prevailing wage, labor certification and labor attestation applications for processing. These are not employer responses to the Bureau of Labor Statistics' Occupational Employment Statistics (BLS-OES) survey.
Any typographical errors or other data anomalies (e.g., incomplete or blank data fields, etc.) may be due to internal data entry or other external customer errors in completing and submitting the applications for processing.
A small percentage of determinations may be subject to change in subsequent quarterly releases due to appeal or redetermination decisions on employer applications.

Injury summaries: OSHA Injury Tracking Application, Form 300A
Calendar years 2023 to 2025Read from the committed copy
While OSHA takes multiple steps to ensure the data collected are accurate, problems and errors invariably exist for some establishments. Efforts are made during the collection cycle to correct submission errors; however, some remain unresolved. OSHA does not validate the employee or injury and illness counts reported by establishments.
Recording or reporting a work-related injury, illness, or fatality does not mean that the employer or employee was at fault, that an OSHA rule has been violated, or that the employee is eligible for workers' compensation or other benefits.
