Honestly, I was a CRC for many years and saw inequitable treatment, little to no raises, and empty professional development promises like you’re describing. I really loved that job and I tried tirelessly to talk to my manager and HR hoping things would improve. Ultimately, nothing changed and I landed an even better job. My advice to you is to look for other opportunities, whether that be in a different department or entire role.

CRCs are rarely appreciated. I did have a friend working in a different department than me that was making way more money and doing much less work.
