The U.S. Department of Labor has sued United States Steel Corp. to reverse disciplinary actions taken against two employees for reporting workplace injuries in violation of the company's immediate-reporting policy and to force the company to amend the policy. The two employees were suspended without pay for failing to immediately report workplace injuries, per the company's policy, according to the lawsuit, which was filed in U.S. District Court in Wilmington, Delaware, on Feb. 17. In February 2014, Jeff Walters, a full-time utility technician at the Pittsburgh steel manufacturer's Clairton, Pennsylvania, plant found a small splinter lodged in his thumb and extracted it himself, according to the lawsuit.
