I resigned a few years back, and was gutted to do so - the reason I left was lack of internal progression opportunities and low-ish pay. They counter offered before I left but I just couldn't stay. It was the right choice, but I was sad to go.
The head of the department has recently resigned and I'm confident I could do that job. I'd love to work with the same team again, but obviously in a different way, in a leadership position.
Has anyone ever done this? How did it go for you?
