To examine the impact of right-to-carry (RTC) firearm laws on firearm workplace homicides (WPHs) in the United States from 1992 to 2017.



We employed 2 longitudinal methods to examine the average effect (pooled, cross-sectional, time-series analysis) and the state-specific effect (random effects meta-analysis) of RTC laws on WPHs committed by firearms from 1992 to 2017 in a 50-state panel. Both methods utilized a generalized linear mixed model with a negative binomial distribution.



From 1992 to 2017, the average effect of having an RTC law was significantly associated with 29% higher rates of firearm WPHs (95% confidence interval [CI] = 1.14, 1.45). No other state-level policies were associated with firearm WPHs. Sensitivity analyses suggest robust findings. State-specific estimates suggest that passing an RTC law during our study period was significantly associated with 24% increase in firearm WPH rates (95% CI = 1.09, 1.40).



This is the first study to our knowledge to examine the link between RTC firearm laws and firearm WPHs. Findings indicate that RTC laws likely pose a threat to worker safety and contribute to the recent body of literature that finds RTC laws are associated with increased incidence of violence.
