Mixed Bag - Sales Director Voltus Employee Review

They hired me from within for the position, so they paid me 25% less than everyone else on my team, who came from outside the company, regardless of years of experience in the industry or in outside sales. I was the #1 person on my team for sales, so after discovering the pay gap, I asked for the deficit to be rectified and the feedback I got when my manager asked the CRO was, I quote, "he is honestly pissed that you even asked" and "you already make quite a bit of money for your age", among other things. I insisted that he ask again and no effort was made at all by the company, so I left. After sending in my resignation saying how grateful I was for all the professional development, both my manager and the CRO kept saying basically that we're not friends anymore and we won't be in touch with you because I went to a competitor. They now reach out to me 3 times a year asking if I want to return. Given the blatant disrespect, I would never return to the company, which is sad because I really enjoyed my time there before that.
