What to do to leave Master-Slave Culture oriented Organisation (TCS)?

Dear all,

I have joined the TCS 3 and half years ago, i come from product based organisations with 13.5 years of experience. Here the culture is poor, no growth and flattery required of the boss. and on paper my salary is 50+ LPA, but i am getting only 28 LPA in hand.

I am trying to switch the job but no one is considering my profile now because of (Gulami Ke Teen Mahine) “The Notice Period”.

Please suggest, what to do?
