I work at a tech company that has numerical levels (as opposed to just "junior" → nothing → "senior") for employees. For the first few levels, you are required to advance to the next level within a set number of months, or you're fired (well, PIPed, so... fired).
I wasn't hired at the base level, and I'd like to move down to it, after learning about this "advance or die" policy. It would mean less money, but that's fine, the company pays a hilarious amount of money to all engineering employees, even at that lowest level. More importantly, I'd receive the same health insurance (fully paid) and time-off benefits, which are what I really care about. I really don't want to lose those entirely, so since moving down a level would allow me to reduce my chance of getting fired, I'll gladly take lower pay for that.
How can I bring this idea up? My company claims that managers don't have much direct control over people's levels and compensation, but I don't know the extent to which that is actually true.
