You may compare with the earlier difinition with this. Earlier the difinition was for specific categories i.e. clerical, managerial etc. of employees and teachers were not covered in those categories. That is why a judgement gone against the teachers. Now the categories have been removed and now all cateogories of employees except apprentice are covered by the Gratuity ACt. You may go through the Amendment Bill passed by the Parliament in which it is clearly mentioned that the objective of the amendment is to cover the teachers under the Gratuity Act keeping in view the judgement of Supreme Court of India.
Accountants, Manager (HR), Clerks are not mentioned in this amendment. It does not mean that these are not covered.
Moreover, the amendment comes into force w.e.f 03.04.1997 from the date from which educational Institutions were covered under Gratuity ACt.
A copy of Bill passed in the Parliament is attached.
