Can you suggest a few inspection firms that provide comprehensive social compliance and labor practice audits?

Yes. If you’re looking for firms that can conduct comprehensive social-compliance and labor-practice audits across supplier/factory operations, these are several established options:

What I'd look for when selecting one

For a comprehensive labor-practice audit, I would ask each firm to quote against the same scope, including:

• Worker interviews and grievance mechanisms
• Forced/child labor and recruitment-fee checks
• Wages, benefits, working hours and overtime
• Freedom of association and collective bargaining
• Discrimination and disciplinary practices
• Health & safety
• Employment contracts and personnel records
• Subcontracting/homeworking
• Management systems and corrective-action verification
• Local labor-law compliance
• Optional environment + business ethics modules

If you want a standardized, shareable audit, SMETA 4-Pillar is worth considering: it covers Labor Standards, Health & Safety, Environment, and Business Ethics. Sedex says its SMETA audits must be performed by approved Affiliate Audit Companies, and its current approved list includes SGS, Bureau Veritas, Intertek, LRQA and others.www.sedex.com

If you tell me the countries/regions you need covered and the industry (e.g., apparel, electronics, food, manufacturing), I can narrow this to 3–4 firms and compare their audit standards, geographic coverage, and typical scope.
