Will TCS Create issues in releiving letter for wfo non compliance in notice period n few months before

Depends on the HR who is taking care of the same when you are in period..Apart from that if you aren't creating any issues from your end like taking unnecessary leaves, unnecessary WFO exceptions,.. etc which increases NP but in later end may lead to situation of delaying your experience letter or giving bad remarks when your NP is closer to the end..Better maintain a good image here in the case of profession with TCS in order to get a smooth exit ...
