If you have been in period of performance incentive and performed as per performance clauses it should be paid as per Payment of Wages Act : Sec2.
An employee can approach the forum for redressal of grievance as per coverage by enactments e.g;
Inspector under Payment of Wages Act (applicable to all employees drawing wages as per def. of wages in the Act up to Rs.18000/pm).
