and I just learned earlier this year that the reason why i haven't been getting substantial salary increases is because I'm outside of the range for my position.

So, it was a good look from the dude that hired me. I started making more than my category. But shit, I've been in the same range for 5 years.

I'm currently trying to get bumped up to the next job category. i need more cheese.

I feel you. i know a few folks that used other job offers as leverage in their current position. I had a homeboy that wanted to do that and I advised him against it. Bc I've seen some employers call your bluff; they'll be like 'best of luck'... Or they might try to match your offer for a while til they find a replacement.
