The United Steelworkers of America applied for certification to represent outside employees of the Township of Michipicoten.
The employer argued the application was barred by an existing agreement with the permanent employees of the public works department.
The Board found the existing agreement was not a collective agreement because the employee group lacked a constitution and formal structure, and therefore was not a trade union.
The Board also determined that an objecting employee classified as a mechanic leader did not exercise managerial functions.
A certificate was issued to the applicant.
