There are three orders of work.
Primary Work is regarded as someone's personal job for their own personal fulfillment.
Secondary Work is regarded as civil service to society (necessary for its health) such as security forces (police), (military training), paramedics etc.
Tertiary Work is regarded as civil duty such as voting, jury, etc.
According to Natural Law and Order based on holistic survival, we are to achieve an optimal level of prosperity (coinciding with our moral principles).
I will elaborate using a scenario.
We will use the age system for the sake of the explanation although all orders will be applied to someone's abilities.
Let's say from the age of 0-10 people are parented in the ways of life and are brought up to be functional members of society, they are educated in the conduct of society, thought basic learning skills and knowledge.
At 10-20 years of age, people begin the informal education process where they are thought the basics of all the fundamental features of society and the universe such as the sciences of physics, mathematics, biology, chemistry, sociology, psychology etc.
At 20-30, People select careers it is a voluntary procedure (primary job (for example physicist), it is changeable) and begin the formal education in said career.
Also, at age 20 people will learn and operate the secondary jobs necessary and it will be mandatory (it will apply under conditions, for example, there are a lack of paramedics etc), although only the best candidates through aptitude testing will be given such work, should there be two candidates of the equal score there will either be a random process of selection or appropriate competitive test to determine the best-equipped members of society to be applied to the job.
At age 30+ People can perform the careers they are capable of.
Although when it comes to working in a limited environment with limited resources such as a laboratory or other facility the best possible candidates will be chosen under the same procedure for secondary work.
People who work a primary job may also be applicable to work secondary jobs.
When a position is available in a facility such a person will be notified and will be requested to work, the person has the option to decline in which case the next person applicable will be given the opportunity.
People who work in a facility will have their work laid out for them by the public as they are a participating member of an agency.
These people will work in a competitive selective environment where they will be held to the highest standards.
A person who is not selected to work in a facility will have the option to work under the conditions of a public library like a scenario where they can utilize the resources available to perform their operations be it mainly independently or within a group etc directives, guidelines and rules for conduct may apply if it is a project or special use of resources etc.
These people will also act as the board of directors as in they will be the administration acting as the scientific consensus and body that direct policies chosen by the public, administrating, moderating and operating the directives, guidelines and rules of conduct for people who work in facilities (based on the standards of the neutral aspects of natural law and order)
The public will govern and be able to contribute to such bodies of work which act like agencies, as a democracy where the public directly decides the policies, for example, the public may create a project to research or create X in which case the people who do not work in the facilities but are educated members of the field and those who function as a group of peers will ensure the policies are enacted upon, according to the neutral aspects of natural law and order.
The Tertiary work will be required for all people to perform.
The NELO aka NLRBE will determine the allocation of resources to agencies and members of whether formal or informal to perform specific projects etc based either upon circumstances of principle or neutral circumstances of opinion when applicable.
This is the system of work I have envisioned for society determined through Natural Existential Law & Order, setting up the RBE.
Work is determined according to lawful priority under the natural order.
