The applicant sought to terminate the respondent union's bargaining rights.
Following a representation vote, the union alleged employer impropriety, including threats of plant closure and holding a barbecue, and sought to set aside the vote.
The Board held that the union was precluded from raising allegations closely connected to the vote itself because it had signed a waiver, and failed to exercise due diligence in raising earlier allegations.
On the merits, the Board found the union's witness lacked credibility, dismissed the allegations of threats, and found the barbecue did not constitute improper interference.
The Board declined to set aside the representation vote.
