In general, I expect most developers aren't working 40 hours and many don't come close. (The amount of upvotes on this thread seems to prove that.) For me, it is hugely dependent on the environment. By the time I left my last position, I was hardly doing any heads-down work. The team was an internal platform team, and the leadership was actively against sourcing any feedback from the eng/data teams we were meant to serve. The only things that were ever on the roadmap was long-term refactors that no one was asking for. My feedback on the direction of the work was by-and-large ignored, despite the fact that I was the only person writing any code on my project. I started a new job and it's been a night-and-day different. Furthermore, the lead engineer of the project is a grinder which motivates me to at least pull my own weight. TL;DR if you're an eng manager and want your team to be engaged, then lead by example, give them tangible goals, and listen to what they have to say.
