It is called fallow period that is left to rest the land uncultivated to allow it to recover and store new nutrients. Professional fallow is the period that a professional lets a company without progress, only fulfilling his duty, without showing initiative or wishes of overcoming. in order to relax physically and mentally.
Professional fallow is incorrectly written and it should be written as "Stage of practice." being its meaning:
It is to be publicizing what they learned, practice it in the field, to convince that you know stuff that is put to the test. It is not question of years of experience to be able to perform a job. To put aside ( Vines. Roses. Etc ) to form future trees and plants, once they leave them roots are ready to be planted, located alone.
