TCS is reputed organisation 

you would be issued experience / relieving letter after service of notice period 

do the job as instructed by your supervisor 

If you have already tendered resignation and are under the notice period, as well as  if your  organization has accepted your resignation, you may have to  inform the top management about the harassment meted out to you.

If you feel that the treatment meted out to you is unjustified  or unreasonable then you may enumerate the events chronologically and make a representation in writing to the top management and seek their intervention to solve the problems and provide you relief. 

If the harassment still continues then you may resort to legal action against the official who is putting you under such troubles.

If they don't issue you can send them legal notice and then complaint to labour Commissioner or labour court

Your query is pre mature.

Let the situation arise first.

If it arises then you can send them legal notice for same. Considering the repute of the company unless you failt miserably while serving notice period it would not refuse giving such experience letter.

Simple is to gain good experience letter and should be relieved in a cordial atmosphere so that next appointment be smooth, so I will advise you that to please don't refuse any work given to you whether out of scope or within scope, do one thing go slow when they ask say trying to complete as work is out of scope , very gently talk.

1. If you do not wish to perform tasks which are beyond the scope of your work then send an email to the HR stating that you will not do this as this is outside your scope of work.

2. Most likely, however, the employer will delay your full and final settlement if you do not fall in line.
