Clock-watcher is an employee who demonstrates lack of interest in a job by watching the time closely to be sure to stop work as soon as the workday or shift is over.

Clock-watcher指对工作心不在焉，总是不停看时间的员工，下班点一到他们就会停下手里的工作。中文可以戏称为“看表族”。

来看个例句：

That new guy is a total clock-watcher. He checked his watch FIVE times in one hour and left his desk exactly at five o'clock.

 那个新来的员工就是个看表族，他一个小时内看了五次表，一到五点立马走人了。
