The applicant union applied for certification and a representation vote was held.
The respondent employer alleged that the union violated the 72-hour 'silent period' prior to the vote through telephone calls made to employees.
The Board found that while two anonymous calls constituted electioneering, they were isolated incidents not attributable to the union, which had taken reasonable precautions to ensure compliance.
The Board concluded the breaches were not widespread or serious enough to influence the outcome of the vote, declined to direct a new vote, and ordered that a certificate issue to the applicant.
