Why there is a misconception that TCS don't fire employees.

My relative has been in TCS and on the bench for 1 year. He is asked to resign today.

Also, tell me whether he should put down his papers or go to labour court.

His manager is not going to give him the project. He was on the bench for 1 year. Today he is put in PIP and asked to resign.

He complained to HR but no use.
