Employee petitions opposing union certification rejected as involuntary due to management interference and workplace circulation.
The union applied for certification.
A group of employees filed petitions (statements of desire) opposing the application.
The Board held hearings to determine the voluntariness of these petitions.
Evidence showed that management held captive audience meetings, questioned an employee about union membership, and that the petitions were circulated during working hours in areas frequented by management.
The Board concluded that the objectors failed to meet the onus of establishing that the petitions were voluntary, as employees would reasonably suspect management involvement.
The Board found the union had the requisite membership support for certification, pending resolution of remaining bargaining unit composition issues.
