Sorry, but I disagree. I work for an academic employer (a supercomputing centre), and the environment that now exists in that workplace is much as Dracolytch spelled out in his second post. We really want to work alongside people who are prepared to think about more than the immediate next step in getting a problem to go away. I'm not a manager, and barring something drastic happening, I will not be in the foreseeable future, but I really value being able to work alongside people who, y'know, care about getting to the root of problems and fixing them in ways that help improve the lot of other staff and our user base. As for whether this is really "passionate", I'd prefer to say something like "thoughtful, considerate, productive and interested in learning."
But I strongly dispute that, in the sense Dracolytch seems to be using it, it means "enthusiastic to the point of being exploitable". We *did* see that sort of boundary violation in our organisation with one manager who was thankfully moved sideways to other responsibilities: key people were being poached from other teams and grossly overcommitted to an endless series of new projects, expected to take on way-out-of-hours problems on office hours pay, with absolutely no formal overtime or on-call provisions (how wonderful it was to receive a text from that manager at 12:30am offering me the root passwords to a storage service the manager wanted to see brought back online when the main admins were on leave, having previously been actively ignored and excluded from that part of the business by the same manager), and generally jerked around like marionettes in a hurricane as the manager pursued his strange agendas of trying to take on any data storage job that would bring in some bucks without any detailed capacity planning or workload modelling. People had to learn on the fly to get things running ASAP; testing was minimal, mistakes were made, and the resulting services were slow and unreliable. It was a very demoralizing time, and everyone was glad to finally see a manager appointed for operations who started planning, listening to his staff and concentrating on delivering a core set of reliable, well-managed services. Even so, everyone still needs to bring a decent level of enthusiasm for fixing problems, building well-engineered systems, looking at the bigger picture, and learning new things. Petaflop-scale HPC and storage is not a turnkey operation, and it's not advisable to kick back and coast along if you are planning to be around when the chickens come home to roost.
