Revisiting the Occupational Health Impact of Right-to-Work Laws: A Research Note.

Area of Science:

• Occupational Health
• Labor Economics
• Public Policy

Background:

• Growing adoption of anti-union legislation, including right-to-work (RTW) laws.
• Increasing trends in workplace fatalities and injuries necessitate examination of legislative impacts.
• Previous research suggested RTW laws negatively affect worker health, but empirical evidence was limited.

Purpose of the Study:

• To reevaluate the occupational health effects of RTW legislation using advanced causal inference.
• To address limitations in prior studies concerning empirical evidence, standard errors, and unobserved confounders.
• To investigate the impact of RTW laws on occupational fatal injuries and other health outcomes.

Main Methods:

• Utilized a 28-year state-year-level dataset from multiple sources.
• Applied an innovative generalized synthetic control method for causal inference.
• Conducted robustness checks with alternative two-way fixed-effects adjustment methods.

Main Results:

• Found null effects of RTW legislation on occupational fatal injuries.
• Observed no significant impact on other examined health outcomes.
• Indicated that previous findings may be based on limited empirical evidence.

Conclusions:

• The occupational health impact of RTW laws is not supported by robust empirical evidence.
• Prior studies may have underestimated standard errors and unobserved confounders.
• Revisiting research questions with updated methodological tools is crucial for accurate findings.
