Who are the actors in this model of labor for pay and volunteerism? Who are the laborers? They are individuals who act of their own free will. They are autonomous decision-makers; the labor in this theory is performed free from force.
Familiarity with labor for money makes the concept easy to accept. However, volunteerism is a newer type of work and deserves a little more attention. Volunteerism functions in conjunction with an individual’s shared interests. People are born to kin and kith; throughout their lives, they regroup with many other shared alliances. These affiliations result in obligations through reciprocity, attention to loyalties and possibly the necessity to exit.
The model requires an acceptance that an individual may pamper the ego and still consider others who fall within their life bubbles.

Suppose one were to write a symbolic notation of labor; one might start by defining L as the number of labor hours the individual allots to paid work and V as the number of hours allocated to volunteerism. If you had a couple where one worked 40 hours a week at a career and devoted 10 hours a week to help in the home, it would be shown as L subscript 40 V subscript 10. Let’s say the other partner worked 20 hours a week at a part-time job and filled in 30 hours to their home life; this would be shown as L subscript 20 and V subscript 30. Or- let’s say that both partners worked 40 and did domestic chores for 10; this could be written as 2(L subscript 40 + V subscript 10)
