When it's time to move off from a stagnant job role, this letter can let employers know that even though you're resigning to pursue new challenges, you enjoyed your time with the company.
I’ve enjoyed my time with the company, but it’s time for me to move on to new challenges.
As you know, I’ve long wanted to explore the possibly of producing widgets via 3D printing rather than plastic injection. When I heard about XYZ Company’s plans for a new 3D division, I couldn’t pass up the opportunity to apply, and I was pleased to secure a role in management. I start there in two weeks.
I appreciate the opportunities afforded to me by ABC Company over the years and wish the best for the team in the future.
