The applicant union applied for certification and submitted membership evidence, including ten cards received by mail.
The employer challenged the weight of the mailed cards because the union's Form A-4 declarant did not personally contact the employees to verify they had signed the cards, relying instead only on the fact that the cards were received in sealed business reply envelopes.
The Board held that without further verification or corroborating circumstances, it would not give full evidentiary weight to the mailed cards.
Consequently, the Board directed that a representation vote be taken.
