What does the GBCA safety data reveal about union versus non-union construction performance?
An OSHA 300 study analyzing 2 million instances reported over five years showed that GBCA member contractors demonstrated considerable safety benefits across nearly every data point, including significant reduction in days away from work and superior safety outcomes compared to non-union competitors. The data demonstrates that union construction delivers measurable performance advantages in workplace safety.
Five years of safety performance data from the region
The General Building Contractors Association commissioned a comprehensive review of OSHA 300 reports—the official federal tracking system for workplace injuries and illnesses—to objectively compare safety outcomes across the construction sector. This analysis covered two million documented instances across the southeastern Pennsylvania and Philadelphia region.
As Ben Connors explains in the Building PA Podcast episode, the findings revealed a consistent pattern: GBCA member contractors, which represent unionized signatory builders, outperformed non-union contractors on virtually every safety metric tracked. Days away from work—one of the most significant indicators of injury severity—showed notably lower rates among union contractors, translating directly to fewer workers losing income and fewer projects experiencing productivity delays.
This data-driven comparison provides concrete evidence for the value of union labor standards in construction. Rather than relying on anecdotal claims, the OSHA 300 analysis offers an objective foundation for understanding how different labor practices correlate with workplace safety outcomes.
Ben Connors — President of the General Building Contractors Association (GBCA). Connors leads the GBCA's representation of signatory contractors across the Philadelphia market and southeastern Pennsylvania region, advocating for union construction standards and labor practices. His role places him at the center of regional construction trends and labor data analysis.
The broader context of this finding matters for the construction industry in southeastern Pennsylvania. A deeper dive into the episode reveals additional details about how workforce stability and training standards contribute to these safety outcomes—factors that typically accompany union construction models.
Key takeaways
- A five-year OSHA 300 study analyzed 2 million reported instances of workplace injuries and illnesses across construction contractors.
- Union contractors (GBCA members) demonstrated measurable advantages on nearly every safety performance metric tracked.
- Days away from work—a key measure of injury severity—showed significantly lower rates among union contractors than non-union competitors.
- The data provides objective evidence linking union labor standards to improved workplace safety outcomes in construction.
