There are many paths to this, and I'm not yet settled on anything quite yet. I am convinced that the Marxist-Leninist branch (basically the USSR and Maoist China and the like) went completely down the wrong path; its focus on a vanguard party makes it particularly susceptible to cults of personality. Not just in the Soviet Union and such, but even much smaller groups aligned with that branch that pop up on college campuses.

A good start is getting everyone unionized. Beyond that, there is lots of theory behind mutual aid (such as (Mutual Aid: A Factor of Evolution)[https://en.wikipedia.org/wiki/Mutual_Aid:_A_Factor_of_Evolution], which also is something of a precursor to kin selection theory in evolution), and Anarcho-Syndicalists also have some ideas on how to organize groups into almost completely flat hierarchies that all work to mutual benefit.
