Employee worried about being overlooked

DEAR HARRIETTE: Over the years, I have become extremely specific with my scheduling, which encouraged me to also become extremely efficient at work. I try to get all my work done within work hours. I generally leave work at 5 p.m. on the dot. I am not doing essential or life-saving work, so I no longer feel the need to overextend myself by staying late to prove my dedication to my superiors.
