**3.2. Intraorganizational SC**

The middle level intraorganizational SC [26] is derived from interactions within the groups, between them, and up to interactions in the whole organization [27, 28]; therefore, it can be conceptualized as a public good rather than a private good [29]. It entails the premise of mutual objectives [27], trust [30] reciprocity [31], respect and appreciation [32], sharing of information and knowledge [33], and common norms [34].

The benefits of intraorganizational SC are better cooperation inside the organization, better employee performance [35, 36], and even better health, physical [37, 38] and mental [39] for members of units and organizations with high intraorganizational SC.
