I quit being a manager but kinda sideways stepped into a different senior (non management) role in the same company/department. I was quite lucky because I didn't really want to leave the company at the time. I just didn't want to be on the trajectory I was on.

It was kinda awkward initially, mostly for the people I had hired and been manager of who I was now colleagues with, but not for long. Hands down it was one of the best life decisions I've ever made. I feel as though the experience I gained helps me to perform my current role even better than I would otherwise be able to as I have an appreciation of the politics above me that I'd not have had I not been up there and back down again the way I have.
