The union applied for an interim order to reinstate 28 employees who were laid off when the employer contracted out its warehousing operations.
The union alleged the employer made representations during collective bargaining that it would not contract out the work.
The Board dismissed the application, finding that the balance of harm favoured the employer.
The harm to the employees was primarily financial and could be remedied by a final order, whereas the employer would suffer significant, unrecoverable financial harm and disruption if forced to reverse its contracting out arrangements on an interim basis.
The union's delay in bringing the application also weighed against granting relief.
