isn't the answer to that question "take it up with HR"? that was very gracious of you to even offer an 80/20 arrangement. Ironically, i bet HR would have a hard time with an 80/20 dual role setup.
I've done it a couple times, at best I ended up leaving, at worst, HR never actually recorded the transfer so when time came a few years down the road, it was on my resume, but come employment verification time, I (and the firm that had offered me a position) learned that archived employee records had me listed down under my prior role, not the one I had transferred into-and had since that point, used for experience in leveraging new jobs. I lost a job offer because of it.
Now I'm reticent to do any kind of 80/20's without written considerations from the company.
I guess I thought I did my best to avoid burning any bridges, but I was actually bargaining against myself.
My position exactly.
I won't be leaving my company, but I will be transitioning to a more defined role in a different department. Didn't sit too well with my current manager. He told me that I couldn't just leave like that. I offered him a 80/20 arrangement, and he didn't like it either.
I'll be transitioning anyway. It's just a bit bizarre that a manager would potentially alienate someone who seems to be indispensable for the operation.
