The National Labor Relations Board is revising in several respects its rules that govern filing and service of papers. The principal revisions include permitting parties to file unfair labor practice charges, petitions in representation proceedings, and objections to elections by facsimile transmission, to permit the Board to serve certain documents by regular mail, rather than by other more expensive means, and generally to reorganize and modify certain portions of the rules pertaining to filing and service. The revisions are being adopted in order to expand the use of facsimile technology to the service of charges, representation petitions, and election objections, to reduce the cost to the agency of the prior requirements that certain documents be served by certified or registered mail, and to update certain other procedural aspects of the filing and service requirements. The intended effect of the revisions is to permit parties and the Board to take greater advantage of facsimile technology, to reduce the cost of serving certain documents, and to update the rules in other respects.
