無時無刻不在談工作的人

A job talker is either someone who only talks about their job with anyone, at any time and in any place, and who has nothing better to talk about than their job, or someone who cannot stop complaining about his/her work whenever there is someone around.

Job talker就是那些無論什么時候、跟誰在一起、在任何地方都只會談工作的人，或者只要旁邊有人就會無休止地抱怨工作的人，總之就是“無時無刻不在談工作的人”。

For example:

I tried to hang out with Jim from accounting last week, the guy is a total job talker. All he did was talk about work for 2 hours.

我上周跟會計部門的吉姆出去玩，結果這家伙只會談工作。他跟我整整說了兩個小時的工作。
