Objective: We estimated associations of a rest break ordinance, implemented for construction workers in Dallas, Texas in 2016, with workplace injuries and illnesses.
Methods: We used workers' compensation claims data to compare changes in rates of injuries and illnesses among Dallas, TX County construction (i.e., "treated") workers with changes in untreated workers, before (2013 - 2015) and after (2016 - 2018) a rest break ordinance was implemented.
Results: Immediately after the ordinance was implemented, rates of injuries/illnesses among treated workers were modestly lower than in comparison workers (Rate Ratio comparing post- versus pre-mandate rates, treated versus comparison workers: 0.89, 95% CI: 0.72 - 1.11). Post- vs pre-ordinance slope trends were similar in the treated versus the comparison group.
Conclusion: Ten-minute rest breaks were associated with modestly lower rates of workplace injury/illnesses. More comprehensive standards may be needed for protection.
