Subcontracting clause restricts municipal employer from letting subcontracts, but not prime contracts, to non-union contractors.
The union referred several grievances to arbitration, alleging that the municipal employer violated the subcontracting provision of the collective agreement by engaging outside contractors not in contractual relations with the union.
The Board interpreted the subcontracting provision, which was imposed during first contract arbitration, as restricting the employer's ability to let subcontracts but not prime contracts.
Applying this distinction, the Board dismissed five of the six grievances, finding that the contracts in question were either prime contracts, involved maintenance rather than construction work, or did not involve work covered by the collective agreement.
One grievance was allowed, as the Board found the contract was in the nature of a subcontract for work that would otherwise have been performed by the employer's own employees.
