The union applied for certification to represent production and maintenance employees at the employer's facility.
Following a representation vote, the parties disputed whether two Shippers should be included in the bargaining unit and whether one of them exercised managerial duties.
The Board found the Shippers did not exercise managerial authority and shared a community of interest with the production unit, thus their ballots were counted.
The Board also ruled that a disputed ballot with overlapping pencil marks in the 'No' window was valid and not spoiled.
As the union did not receive more than fifty percent of the votes, the application for certification was dismissed.
