The statutory protection of the right to vote implies that there must be a reasonable opportunity to vote. Thus, there is an obligation on the labor organization to conduct its periodic election of officers in such a way as to afford all its members a reasonable opportunity to cast ballots. A union may meet this obligation in a variety of ways, depending on factors such as the distance between the members' work site or homes and the polling place, the means of transportation available, the nature of the members' occupations, and their hours of work. A reasonable opportunity to vote may require establishing multiple polling places or the use of a mail ballot referendum when the members are widely dispersed. It would also be reasonable for the time period for voting to be extended to accommodate members who might otherwise be prevented from voting due to conflicting work schedules. Shortening the voting period by a late opening of the polls would not, in itself, be improper unless the intent or practical effect of such action is to deprive members of their right to vote.
