In a representation vote you can only vote for representation. If you don't want representation you don't vote. A ballot voting against representation would be void
In a Telephone, Internet or Mail Vote.
You need 50% +1 of the eligible voters to vote for representation in a representation election. All that matters is did 50% +1 of the eligible voters cast a valid ballot for representation. You cannot cast a vote for no representation you cannot cast a vote for the Company you cannot vote for yourself. Those ballots would be voided. The voters ballot must show clear intent to vote for representation.
If a majority (50%+1) of eligible voters vote for representation then the organization or individual that received a majority of votes cast for representation will be certified as the representative even if that organization or individual did not receive votes from a majority of the craft or class.
When a majority of the eligible voters have cast valid ballots, but no single organization or individual has received a majority of the votes cast, a run-off election may be held.
In a run-off election, the ballot includes only the two representatives receiving the greater number of votes cast in the initial election, and does not include a space for write-in votes. The representative receiving the higher number of votes in the run-off is declared the winner even if fewer than a majority of the eligible employees cast run-off ballots.
