HB 841 -- Workers' Compensation Sponsor: Secrest Under current workers' compensation laws, an injury is work related if work was a substantial factor in its cause. This bill requires that work be the dominant substantial factor in causing an injury before it will be considered work related. The bill also limits workers' compensation recovery for the aggravation of a pre-existing condition to the extent that the work-related injury causes increased disability.Copyright (c) Missouri House of Representatives
