Hello Friends,

Recently my project got changed and the whole roles and responsibilities too. I'm not satisfied with the work I am doing and no future also for it as per my understanding.

Salary is main concern for me and for my family commitments. My current package is around 9LPA (Including fixed ,Variable and bonus) for 6.2YOE role is IT analyst. My family wants my support, no WFH/ hybrid also allowing here.

Requesting you to please suggest can I resign and search for a new job.Because of this 90 days notice period i am not getting calls also my bad.

If not get job in 90 days , can I take my resignation back In TCS? Is anyone aware of it please reply ..

Thanks a lot for suggestions in advance.
