Impersonal relationships are due to job specialization

I believe the answer is: organic solidarity

Organic solidarity refers to a social relationship that created because people are depending on one another in order to pursue one similar goal.

This could be seen in job specialization in which one division of workers wouldn't be able to complete their job properly if the other division do not finished their parts.

they all focused on themes about the inevitability of death.

new communications technology has affected the way social movements are organized because nowadays, social movements rely on social networks and the media to get different people with a similar way of thinking in contact, and thus, get them to mobilize for a greater cause.

individuals only participate in collective action when they feel identified with it. is in this aspect that social media becomes relevant, because it guarantees communication among all individuals and organizes the social actions that are going to be carried out, i.e., the social movements.

in addition, being covered by the media is important to validate the message and make it relevant in the social agenda, as well as to reach more people who can share interests, appealing to public sympathy for their cause.

in conclusion, it is by social networks and social media that social movement is given birth; by connecting different individuals with similar ideas and organizing them to mobilize for a greater cause.
