Transportation Management: The Employer Bore the Same-Decision Burden After Protected Conduct Motivated Discharge

By Aneeta Mishra and Timothy Chan

Published August 22, 2026

NLRB v. Transportation Management Corp. reviewed the discharge of a bus driver who supported a union while the employer asserted rule violations as the reason for termination.

The General Counsel first had to prove protected conduct mattered

Knowledge, timing, hostility, shifting explanations, and comparative treatment could support a finding that union activity was a motivating factor in the adverse action.

The employer then carried a same-decision burden

The Board could treat proof that the discharge would have occurred anyway as an affirmative defense rather than forcing the General Counsel to disprove every lawful reason.

The allocation fit the NLRA

The Court accepted the Board’s construction of the statute and its remedial role in separating unlawful motivation from independently sufficient misconduct.

Current Board doctrine must be checked

NLRB causation standards and burden frameworks can evolve through later cases and agency decisions. The governing rule at the time of the dispute controls.

Key takeaways

• Preserve evidence of protected activity and management knowledge.
• Compare discipline for similar misconduct.
• Document the decision timeline and contemporaneous reasons.
• Apply the Board’s current causation framework.
