45 U.S. Code § 797e - Assignment of work
With respect to any craft or class of employees not covered by a collective bargaining agreement that provides for a process substantially equivalent to that provided for in this section, the Corporation shall have the right to assign, allocate, reassign, reallocate, and consolidate work formerly performed on the rail properties acquired pursuant to the provisions of this chapter from a railroad in reorganization to any location, facility, or position on its system if it does not remove such work from coverage of a collective bargaining agreement and does not infringe upon the existing classification of work rights of any craft or class of employees at the location or facility to which such work is assigned, allocated, reassigned, reallocated, or consolidated. Prior to the exercise of authority under this subsection, the Corporation shall negotiate an agreement with the representatives of the employees involved permitting such employees the right to follow their work.
The authority granted by this section shall apply only for as long as benefits are provided under this subchapter with funds made available under section 797
