Being a line engineer can also have bad micromanagement and bad priorities, while also paying less.
It's funny to say you don't like "constantly doing adult daycare" and conclude that it is better to be the one being adult daycares for instead.
The worst part of the two gigs I had was the director who was in the position above me? Not moving. In both companies. I spent almost six years between two companies trying to find a way out of middle management. I finally realized a lot of companies structure gets flat very quickly because a lot of the upper level executives are not moving, or not getting promoted, so then you have another set of issues you're dealing with.
Its just not worth it unless you can get in and get out of middle management in less than 2 years.
