At the time of the election the name of each employee voting shall be recorded by his signature written beside his name on the voting list for the polling place at which he votes. Each certificated employee may cast only one ballot in any election held pursuant to these rules, and the presence of a signature beside the name of an employee desiring to vote shall automatically constitute grounds for challenge to his right to cast a ballot in an election.
