Union certification granted; peer pressure from rank-and-file employee did not invalidate membership evidence.
The applicant union applied for certification and filed an unfair labour practice complaint against the respondent employer.
The employer alleged that the union's membership evidence was unreliable because an employee had threatened another employee with job loss and higher initiation fees if he did not join the union.
The Board found that the employee who made the statements was not acting as a collector or agent for the union, but was merely a rank-and-file employee trying to influence a friend.
As peer pressure does not invalidate membership evidence, the Board found the evidence reliable and granted the certificate.
The union subsequently withdrew its unfair labour practice complaint.
