对于同事间寻求帮助，室内的礼节往往起着重要的作用。往往没人愿意帮助那种老是无法完成自己工作，爱偷懒的人；而大多数人还是乐意主动地帮助那些曾经也帮助过自己的同事。

If you know a coworker is working through lunch to collate a large client packet, your volunteering to stay and help will be gratefully received and most often returned when it's you who is stuck. I say voluntarily ause your offer is not to add up paid overtime hours. It is to help a peer in need.
