The applicant union sought certification for a bargaining unit of plant guards at the respondent's South Plant.
An objecting employee argued for a two-plant unit, but the Board found the single-plant unit appropriate.
Objectors also alleged that a rank-and-file employee who collected membership cards misrepresented that a representation vote would be held.
The Board found that the misrepresentations were isolated incidents, corrected in some cases by union officials, and did not reflect a widespread pattern that would undermine the reliability of the membership evidence, which exceeded 70%.
The Board granted outright certification without a representation vote.
