There's a story by Feynman where he automates some simple thing on his first job. It was some kind of telephone system, and he attached strings to the lines so he could see where the call was coming from in another room. And he got in trouble for it because his boss didn't understand it or appreciate it. The moral of the story was that people don't generally like innovation or change. Especially if it's just your time being saved and not theirs. If you can get away with it, don't tell your employer.
