Yard

This groundbreaking agreement guarantees that SMART-TD members working in train and yardmaster service will have job protection for the length of their careers following the transaction, subject to the usual requirements for continued employment. Union Pacific has committed that these employees will not face involuntary furloughs as a result of the merger. This is an unprecedented guarantee in the history of American railroading.
