I used to be a QA Analyst at a call center and I was one of the few SME's in the entire call center. I was trained on all of the products and many of the supervisors and team leads would ask me questions regarding the products all the time.

The reason I quit my job is because there were agents who were less qualified than I was who were making more than me and I was responsible for auditing their calls which requires the use of my knowledge to do. I asked for a raise several times and even threatened to go back to taking calls because I could actually make more money that way. They finally gave me a raise but I was still making less than some of those agents.

I applied for another job in a different industry making significantly more money. I interviewed and got the job. I'm still working for that company and it is by far the easiest job I've ever had and way less stressful. I was very hesitant on quitting my old job because sometimes the grass isn't greener on the other side but in this situation it was.
