Is it true that TATA doesn't layoff their employees???

either you guys are too young or had fall for Tata PR. TCS has fired thousands of people in 2014-15. It was big deal that time and main thing there was no need of that. They had given 1 time big bonus after that just to get in good book of employees.

unless you do something like fraud or harrasment kind of thing , NO

One of the safest companies to work with but no hikes. Do negotiate for salary i know they hired one my reportee at 300%
