This study estimates union effects on workers' compensation indemnity
claims in 1977-92, based on individual panel data constructed from the
March Current Population Survey. Union members were substantially mor
e likely to receive workers' compensation benefits than were similar n
onunion workers, and they were more sensitive to variation in benefit
levels and waiting periods. The authors suggest that differences in un
ion, as compared to nonunion, workplaces arise because workers are pro
vided with information from their union representatives, supervisors a
re more likely to inform injured workers about workers' compensation f
iling procedures and less likely to discourage workers from filing cla
ims, workers are less likely to fear being penalized for filing claims
, and management has less discretion and ability to monitor workers an
d penalize them for questionable claims. The findings suggest that com
munication of relevant information to workers is an important determin
ant of workers' compensation recipiency.
