Query

Employee has right to demand for minimum wages or the wages on par with the employee working in the same position ( part of equal wages) but no where mentioned about the annual increment.  However suggest to appriase your status to HOD / HR or the MD of the company & in case they didn't respond then better to look for alteratives as you worked for more than 1 year 7 months with out any increment / benefit.

GO thru all service related documents carefully e.g. job advt, interview call letter, offer letter, appointment letter, any rule/policy mentioned in appointment letter e.g. HR policy/Service Rules/Employee handbook, certified standing orders and look for words like apraisal/wage revision etc.................

It is the duty of bosses/HR to initiate and conclude appraisal before due date.

If your position is covered by Min.Wages Act then look for notifications issued by o/o Labor Commissioner.

The employees representative/union/GRC/Works Committee/Trade Unions can negotiate wage revision with employer.

Change if you are not satisfied.
