Answer:
The <em>fundamental reason medical doctors and clinical psychologists require license for their operation lies in the fact that they deal with human health</em>. Without licensing, the risk that some of such professionals would follow wrong line of treatment, which may lead to serious harm to the patient's health or even death, becomes much greater.
It could be said that Industrial and Organisational (I/O) psychologists do not deal with the health of the employees on such a level that may cause harm. Meanwhile, let us <u>take the case with occupational burnout</u> - a salient issue in both corporate, governmental and non-profit organisations. Though, occupational burnout is not a medical condition, it may lead to such issues as depression, anxiety and sleep disorders. These conditions in their turn can lead to serious health problems and even attempt to end own life.
Now, imagine I/O psychologist with poor education and training who has strong influence on a given employee and does not advise this employee to address mental health professional, while he or she need it. It puts employee’s health at a great risk. That is why in Australia, for example, I/O psychologists are required to have a licence.
