What are Professional Bodies and what is their significance

A professional, SANS his professional body, is nothing but an ordinary low-skilled worker .

What is the difference between a professional and an ordinary low-skilled worker ?
The professional is a worker too, in a sense like any other worker, albeit a high skilled worker.
What marks the difference between a high skilled and a low skilled is that - a high skilled worker acquires his craft not-naturally, but by immense training and learning process. A low-skilled worker is someone whose skills are abundantly available free in nature, and are such as to come to him intuitively ,without any great efforts.

So, how does a high skilled worker transform his skills into a economic success ?
There is the question which leads us to understand the significance of a professional body ( an association, a guild, an Institute, or a livery company) . A professional body exist in various forms, depending on the scale and the associated negotiation clout it may hold.
The primary function that a professional body perform is to set the standards of wages, which it judges usually to be above the low-skilled person wages.

But how does a PB declare the fair wages standards?
The strength is derived from the length, breadth and depth of its knowledge in the professional and every aspect that touches it. The length refers to the knowledge from within the profession. The breadth refers to the comparitive knowledge from other professions. And the depth, ofcourse,is the knowledge of the intracies.

How does a PB lay claim over the length, the breadth and the depth of knowledge ?
By having within its membership,a very large count of persons exercising the profession and at the same time have parallel or extended interests in other fields.

How does a PB judge the fair wages ?
To do a calculation for what should be the fair wages, it needs to set the standards for fulfillment of various tasks entailed in the profession. Once that is done, it sets standards for the time and learning standards which must be met in order to acquire the skills. Corresponding to this, the wages are judged at the rates obtained from with the help of rate charts of foundational goods and service built collectively by their respective controllers.
The method is simply of apportionment of the cost at various stages.

How does it manage to ensure that it's standards are not challenged or competed by any other PB on a parallel run ?
The PB does so by monopolosing, ( for example, exclusive rights by the Royal Charter given by the monarch of England) the role of the standard settings agency.

Is such a monopoly not a bad idea ?
No. Because a PB declares merely the standards. It is not a trade union or a labout union which is negotiating with various employers the wages and other standards. The fair wages are not same as the market wages. Market wages are fair wages further with the market demand and supply factors. The PB announces the optimal count of the professional  persons required in the industry at any time. 

What if the standards that a PB has set are not appearing satisfactory to someone ?
The PB is NOT A POLITICAL outfit which is trying to achieve its ends by gaining power, through political justice.
PB declares the standards after thorough research and academic pursuits. That is to say, the standards are representing the RIGHTEOUS CHOICES and not the POPULIST CHOICES.

Therefore, if someone is not satisfied, the PB will only proceed to enquire the causes of dissatisfaction, and find a logical conclusion to his query. Even if it is to dismiss a stated cause, the reasoning will be justly provided and homogeneously applied in all cases similar to that. Ofcourse, the PB will have to give recognition to the various Schools of Thoughts in a subject matter if more than one view appears to be satisfactorily explaining a  certain question. A PB does not diffuse or suppress any view for prejudicial want of making one view look superior to another. A PB therefore strives to work by consensus.

How does a PB achieve consensus when every person has different beliefs, and they even has a legal , fundamental right to hold different beliefs ?

All PBs are suppose to engage in setting the Standards related to that profession. In doing say, since the standard by its definition means one unique parameter,homogeneously applied everywhere and  everytime, therefore leaving no room for multiple standards, are bound to work by consensus. Consensus means ALL people agree to a given idea. Even a slightest disagreement, if it is satisfying the logics, can mean multiple standards. Therefore to find the consensus , multiple schools of thoughts are allowed, if each of them is confirming to the standards of logic. Intensive academic research leads to the finding of consensus. Consensus is a logical satisfaction, not an arbitrary, prejudicial action or reaction.

Is a PB same as Labour Union ?
A PB is not at all a Labour union. The professionals are supposed to be hired, not employed by an employer. Therefore there is no collective bargaining done by professionals, the ordinary workers do the Collective bargaining.A professional receives "a fee" for his services, not "wages". And the "fee"  is in accordance with the standard rates set by his PB. 

How does a PB manage to keep off the realpolitik conducts within its own working ?
It's pursuits are purely academic. And therefore, the foremost thing it has to avoid is the arbitrariness and discretion. All its action and choices and rules have to be REASONABLE. The standards of a good, consensus forming REASON is its OBJECTIVITY, and not Subjectivity. Objectivity means those measurable by some physical means, or perceivable by human sensual organs, not to his beliefs.
