I have requested a pay increase and/or title change for over 3 years. I am always told that my job description fits my title and the decision is not up to my manager. I have been doing 3 other people's work since 5 people left my department last year during the Great Resignation. They left because they were offered a larger salary from other employers. My salary is at least $20k below the average, but I stay because the PTO and benefits are good. I dread starting over after being with company for 14 years.
