The union applied for certification to represent a unit of vaultmen, messengers, drivers, and guards employed by an armoured car company.
The employer argued that the employees were guards within the meaning of section 11 of the Labour Relations Act, and that the union was ineligible to represent them because it admitted non-guards to membership.
The Board applied the conflict of interest test and found that the employees' duties did not raise a real possibility of a conflict of interest with other employees.
The Board concluded that the employees were not guards within the meaning of section 11 and granted the application for certification.
