Many people use to call someone a ‘Professional’ if a person is an expert in a field. The Cambridge dictionary defines ‘Professional’ as a person who has a job that needs a high level of education and training.
We’re trained to be a professional at the universities. We’ve learnt the word ‘Professional’ does not only refer to anyone who earns their living from performing an activity that requires a certain level of education, skill, or training. A professional requires the standard of competency, knowledge, or education adhering to codes of conduct and ethical standards.
One cannot be a ‘Professional’ unless one has and maintains ethical principles in concordance with the societal and legal framework. Without ethics, one cannot call oneself a ‘Professional’. (Notes from Project Management and the Professional: Lecture 3 – G.Mooney)
According to The Australian Council of Professions, a ‘Professional’ is generally seen as an indicator of integrity, ethics, trust and expertise.
