The 70-20-10 Rule—Developing the great leader in you: Did you know 70 percent of learning and development should come from on-the-job experiences, 20 percent comes from feedback, observation and working in coaching and mentoring relationships, and 10 percent from formal learning such as classroom training?
Between the lines: we don't want to exert the time or spend the money to properly equip you to handle the job and overcome the problems and obstacles you'll face on a day to day basis. Suck it up, and you'll learn it all as you go along.
I can understand the numbers, to a point. Not everybody thrives, or can be successful, when just getting tossed to the lions however. I'm sure alot of people have quit, or been fired, from jobs because they weren't prepared to handle the on-the-job experiences.
