Following a positive last offer vote, the trade unions refused to execute a collective agreement, citing concerns over a last-minute statement by the employer.
The Board previously ordered the unions to execute the agreement and scheduled a hearing on damages.
The employer claimed over $700,000, primarily for security services and truck rentals during the strike.
The Board held that compensation is not automatically awarded from the date of a vote if a union has a good faith objection.
However, the unions were held liable for damages incurred after the Board's initial decision was released, as they continued the picket line and condoned misconduct.
The Board awarded $13,093.19 for truck damage, truck rentals, and a portion of the security costs.
