After working for a company for 7 years, I assumed that my salary would be increased depending on my performance which was top notch. Every year I got minimal increase for inflation but never any significant increase that was commensurate with my performance.

Finally I decided to look elsewhere to see how much I would get paid and was surprised to get an offer that was 50% more than what I was making. When I told my current employer they said they would match that pay.

Moral of the story. You will not get salary increase unless you actively ask for it.
