<prompt> Human: Ive been working for this business for nearly 4 years now. When I first joined I was moving up from a low paid retail banking role circa 19,000 and when I was offered this job they wanted to take me in at 21,000. I negotiated up to 22,500 and took the job.My pay is based on my sales performance and I have been the top salesperson for 2 years running now. My take home last year before tax including commission and bomuses was circa 53,000.I have had wage increases each year in line with inflation.From conversations with colleagues I suspect that my basic is less but I havent outright found out what they are on. I suspect its anything from 25,000 to 30,000.What is my best negotiating tactic to get a higher basic wage?  <response>: Show them proof of the fact you are outperforming your peers, and think you deserve a pay rise. The amount that your colleagues are being paid should not be brought up or used in this conversation.If you get denied, look for a new job. Loyalty means fuck all in this day and age.
