I accepted my current job with a six-month salary review. Approximately three months into working, it leaked out to one of my supervisors that I was unhappy and I was offered a $3,000 pay increase. (I would assume as incentive to keep me working there.)

The supervisor who offered me the pay increase has since been laid off. If I'm still at my job at the end of six months, is it still fair to request the salary review, even though my pay has already been increased due to unexpected circumstances?

Thank you.
