This article demonstrates that the shortage of employment experienced in African societies, particularly the Democratic Republic of Congo (DRC), gives rise to two problems in the practice of recruitment, ethnostructure and ethno-employment, which constitute the impediments to the proper functioning of the organization. To overcome these issues, the "Rainbow Recruitment" (RAEC) method is proposed, which should not be confused with the name of a French temporary employment company. Through six stages, the method allows the company to build a staff who would represent the different cultural communities of the company in such a way that they give the impression of the colors of the rainbow. Apart from recruiting staff, the CEAS can also be used in the composition of members of state institutions. Thus, successful social innovation in recruitment strengthens social cohesion between cultural communities, restores well-being at work, social peace and improves individual and organizational performance.
