Let me have an engraved tip.
being inscribed to an order does not involve being in a "protected market", anything else.
is a free market like all the others, with economic references (tariffs) on what to do. among the free professionals that I know the only ones who (maybe) do not argue are those who work as consultants of the courts.
is similar to the market of construction companies, which to be "confrontable" express their competitiveness through a number (low) on standardized reference performance.
but who is enrolled in an order, must respect a set of rules. if you do not behave deontologically well you can be suspended, if you do not pay the registration fee you can be suspended, if you do not have professional insurance you cannot operate, if you do not have continuing training you cannot operate... and above all a professional enrolled in an albo, when he signs, he assumes the civil and criminal responsibilities of what he has subscribed.
not for 1 month or 1 year, to life.
and to sign up for an order, you have to take a qualification exam (succedaneo a diploma or graduation) generally preceded by a period of apprenticeship that lasts several years.
I believe there is a considerable difference with an unwritten ing, which among other things must not even sign what he does (and therefore assume responsibility).
p.s. what is written is for the building/plant sector, for hearing it is also for the legal and for the doctor. I don't know if it's the same for the mechanic,
