Staying until the end of the day when your work is complete should not be a sign of a good employee. If the work is done well, nothing else should be questioned. Staying late is a sign of poor boundaries between work and life, nothing more and nothing less.

Thankfully, in this story, we have the rare instance of a good manager who knew how to protect her employees and their valuable time.
