The voting hours (during, before, or after working hours) are arranged so that all eligible employees on all shifts and at all locations have an adequate opportunity to vote. Even though employees are not entitled to vote on during work hours, the employer usually permits employees to do so. If there is one shift and all employees work the same hours, the voting time is scheduled to allow employees to vote at the start or close of the workday, or on a lunch break. If there are two shifts, the most convenient method is to open the polls over a period that will straddle the shifts. Thus, if the first shift is 7 am - 3 p.m. and the second is 3 p.m. - 11 p.m., the polls may be open from 2:30 to 3:30 p.m.. If there are three shifts, the voting times straddle any two of the three shifts in the same manner as the two-shift example.
