Its customary for workers to get cost of living increases periodically in their paychecks, so its not a turn-off for me. However, everything in perspective, so it depends on the amount of increase and whether I feel the service is worth the increase. Its a fair market so if the price is not right for you, move on to someone else. But price increases in and of themselves is acceptable . Would you want to remain on YOUR job forever without a pay raise ?
