A labor organization may comply with the election notice requirement by publishing the notice in the organization's newspaper which is mailed to the last known home address of each member not less than fifteen days prior to the election. Where this procedure is used (a) the notice should be conspicuously placed on the front page of the newspaper, or the front page should have a conspicuous reference to the inside page where the notice appears, so that the inclusion of the election notice in a particular issue is readily apparent to each member; (b) the notice should clearly identify the particular labor organization holding the election; (c) the notice should specify the time and place of the election and the offices to be filled; and (d) a reasonable effort must be made to keep the mailing list of the publication current.
