Prior to the early twentieth​ century, a worker who was injured on the job could collect damages only by suing his employer. To sue​ successfully, the workeror his​ family, if the worker had been killedhad to show that the injury was due to the​ employer's negligence, that the worker did not know the job was​ hazardous, and that the​ worker's own negligence had not contributed to the accident. These lawsuits were difficult for workers to​ win, and even workers who had been seriously injured on the job often were unable to collect any damages from their employers. Beginning in​ 1910, most states passed​ "workers' compensation" laws that required employers to purchase insurance that would compensate workers for injuries suffered on the job. A study by Price Fishback and Shawn Kantor of the University of Arizona shows that after the passage of​ workers' compensation​ laws, wages received by workers in the coal and lumber industries fell.
