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就是那些无论什么时候、跟谁在一起、在任何地方都只会谈工作的人，或者只要旁边有人就会无休止地抱怨工作的人，总之就是“无时无刻不在谈工作的人”。
