I've outworked many during my normal workday that made a name for themselves as overachievers on the time clock. Some guys have to work late on occasion but the ones that consistently stay later than everyone else are doing so for the sake of staying late or because they can't manage their time during the day.
Again, my experiences.
It's more of a figure of speech, the "first one in, last one out." It's not even actually always true. It's a shorthand way of conveying someone goes the extra mile, does anything they can to get better.
