CSX Transportation Inc. retaliated against an employee at its Selkirk, N.Y. facility who reported safety concerns to management.

The employee, who was a union official, on Sept. 6, 2013, gave the plant superintendent a letter detailing alleged safety hazards and violations of the Federal Railroad Safety Act (FRSA). In the letter, the employee also expressed the union’s intent to withdraw its support of the plant’s safety committee, OSHA said.
