what does he mean by performance? coz there is nothing to measure it? he has to clarify about what he is expecting..... coz most of the time, this salary increase never happens..... this happened to me also... the salary increase which i was promissed after 3 months, i got it after more than 16 months.....

so clarify it before itself or tell him to compelsorily increase the salary after 3 months and if at all he says that your performance is not good then ask him to send you back.....

nd if ur satisfied with 2000 for 2years then nothing to worry.....
