You are right, because sometimes if the person are not getting the way he was getting before from the job, you will start losing interest that job that is what happen with some people with their jobs, them will start losing interest about the job.We almost experienced the same thing. I was working on an organisation and I was satisfied with the pay they offered at that time. But as time went on, I was given higher responsibilities but not higher pay. Even though they increased, it was not up to my expectations. I started losing interest in the work and I don't even know when I finally stayed back.
