Summary

William J. Brennan, Jr. Sinkler v. Missouri Pacific Railroad Company…

Hence a railroad worker may recover from his employer for an injury caused in whole or in part by a fellow worker, not because the employer is himself to blame, but because justice demands that one who gives his labor to the furtherance of the enterprise should be assured that all combining their exertions with him in the common pursuit will conduct themselves in all respects with sufficient care that his safety while doing his part will not be endangered.

William J. Brennan, Jr. Sinkler v. Missouri Pacific Railroad Company…

Thus while the common law had generally regarded the torts of fellow servants as separate and distinct from the torts of the employer, holding the latter responsible only for his own torts, it was the conception of this legislation that the railroad was a unitary enterprise, its economic resources obligated to bear the burden of all injuries befalling those engaged in the enterprise arising out of the fault of any other member engaged in the common endeavor.
