In some rare cases, a resigning employee might want to lay out the ways in which they weren't appreciated by management or a corporation. This letter template suggests some wording.
In light of our recent conversation, I am submitting my resignation effective two weeks from today.
I remain proud of my work for the company, including leading my department to record sales, increasing efficiency by successfully upgrading the widget production line, and increasing customer satisfaction by 14%.
It’s disappointing that my accomplishments are not seen in the appropriate light. Regardless, I have already secured a position at a top competitor and wish you all the best in the future.
