Key legal question
Whether the dismissal was abusive because of union-related activity or involvement in the night-work credit dispute
Extracted holding
No. The employer had no knowledge of any protected union role, and the dismissal was motivated by acknowledged employment breaches, not by union activity.
Extracted reasoning
A dismissal is abusive only if the protected activity was the actual motive. The court found no evidence that the employee acted for the union vis-à-vis the employer, and the employer lacked knowledge of any hidden role.
