Except in cases of emergency as provided in this section, the employer shall give reasonable written notice to each recognized employee organization affected by any law, rule, resolution, or regulation directly relating to matters within the scope of representation proposed to be adopted by the employer, and shall give such recognized employee organizations the opportunity to meet and confer with the administrative officials or their delegated representatives as may be properly designated by law.
