The applicant trade union applied for certification in the construction industry.
A group of employees filed a petition objecting to the certification.
The Board found that the objecting employees, who were unrepresented, failed to adduce first-hand evidence regarding the origination and circulation of the petition, and failed to account for its custody.
Consequently, the Board gave no weight to the petition.
As the union demonstrated membership support of more than 55 percent of the employees in the bargaining unit, the Board granted the application and issued the certificates.
