Do you agree INDUCTION or ORIENTATION is compulsory for all staff before starting work for any organization?

the new comers orientation is more than important and it's for the organization's benefit in the first place so it's compulsory for the organization it self to have it for its new staff 

Yes, and should be done depending on employee level and responsibilities.

Downright very necessary to use the definition of an employee with the staff to break the barrier of shame or to enter the work faster
