Dear Pavani,
As per the Industrial Disputes Act, if the strike is legal (that is, if the notice has been given by the union that they will be going on strike before the commencement of the strike, then the workers are entitled to wages). However, if the strike is illegal and no prior notice has been given, then no workers are entitled to salary, and hence their wages are to be cut.
I am also attaching the Industrial Disputes Act material so that the answer can be more clarified...
Regards,
