I think the first paragraph and venn diagram described the problem pretty well. This is why I'm a huge advocate for not giving a shit beyond the scope of what you control or are getting paid to do. Devote your day to the thing you're working on, but it's not in your favor to do more than that if you don't control any other aspects of how that hypothetical extra time is rewarded. If you get unlimited overtime pay, great, spend as much time as you want getting it, your reward is more money. If you're not, and don't have a stake in the company, and never hope to, or don't have anything but a guarantee you'll land that promotion, devoting more of your mental energy beyond the time you're paid for is just a recipe to be Jason Bateman. No amount of loyalty will be rewarded with not being laid off, so assume you will eventually, negotiate aggressively, and leave earlier than later if your work isn't rewarded in the way you feel like you can get elsewhere.
