Dear Mr Ratnakar,
First of all there is no connection between increment and resignation.If the anniversary increment is effected in your company on 1st of Jan'12 but regularised on 1st of Nov'12 towards your rendering the services, irrespective of the fact that you resigned subsequently which was accepted by the management also, you are eligible for the arrear increments for the period it was not effected till the date of your separation and this should have been in fact cleared along with your full and final settlement.
