The applicant union applied for certification in the construction industry.
The employer filed a list of employees, and a group of employees filed a petition opposing the certification, including some who had previously signed union membership cards.
The Board inquired into the voluntariness of the petition, which was circulated by a working foreman who, while not managerial, had a special relationship with the employer.
The Board found that the foreman's involvement could reasonably influence employees to sign the petition to avoid exposing their union allegiance.
Consequently, the Board declined to give weight to the petition and certified the union based on its documentary evidence of membership.
