I can tell you the impact of salary cut of the employees of TCS on TCS. These are as follows.
1) Big attrition means big crises skilled employees. 2)Due to attrition there quality will go down due that there profit will also go down. 3) Company most part of revenue will go in training of newly hire employees.
BEST SOLUTION FOR TCS(If they are incurring loss and before sending communication of employees). 1)They should hire fresher from some IT college and trained them properly for replacement of old employees. 2)They shouldn't reduce the variable pay, they should not give hike to the employees as they are giving at the moment.
