Orientation program

Of course it helps. Orientation programs are meant to make the new employees familiar with company culture, etiquettes, technologies, HR and other policies etc. I don't see this as a debate topic.

yeah sir i also agree with above statement but when i chat with two of my friends one at hero honda company,he said that orientation program is necessary and other at some other company said that if new person goes to a company in the position of middle low management ,then he needs a full orientation program but if he has more than 10 years of experience and about to fulfill upper management then he should not given a full orientation program

these two different views confused me

The nature of orientation program is different for employees at different levels in hierarchy. The junior level employee may not be given the same information as a higher level employee. The point under discussion is whether the orientation program is necessary - the answer is yes. The orientation program makes an employee familiar with the new environment he/she will be working in.

Yeah the Orientation called Induction program is required!
It helps in understanding the processes and rules pretty effectively.
As Biggie said different level of people will be given different kinds of orientation sessions!
