上海市番禺中学的晓星同学问: 最近,我老是在报纸、杂志上看到“灰领”这个词。以前我只听说过“白领”“蓝领”,后来又好像有什么“金领”,现在又来了个“灰领”,可真把我搞糊涂了。这个“灰领”到底指的是哪一种人昵?它和“白领”“蓝领”“金领”那些“领”们又有什么区别呢? Hsing Hsing, a student at Panyu Middle School in Shanghai, asked: Recently, I have always seen the word “gray collar” in newspapers and magazines. In the past, I had only heard of “white collar” and “blue collar”. Later, it seemed that there was a “golden collar”. Now there is a “gray collar,” which really confused me. What kind of person does this “gray collar” mean in the end? What is the difference between “white collar”, “blue collar” and “golden collar”?
