辦公室這一類的工作
這一支就是領子本身：用白領子代表整類在辦公室做的工作。
adjective · B2
Used before a noun to describe work, workers, or jobs in offices, banks and similar places, rather than work done in factories, on building sites, or with machines.
白領的；辦公室工作的
核心畫面
Picture the top of a shirt. One collar is white and stays clean all day, because the work is papers, screens and meetings. The other collar belongs to a tough work shirt, because the work is hands and machines and dust. English picked up that one small detail — the colour at the neck — and used it to name two whole worlds of work. Once you see the collar, everything the word does follows: it tells you where the work happens and what it is done with, and it says nothing at all about who matters more.

可以想成一件襯衫的領口。一邊的領子是白的，一整天都保持乾淨，因為做的是紙本、螢幕和開會。另一邊是耐磨工作衫的領子，因為做的是手、機器和灰塵。英文抓住脖子上這一小塊顏色，拿它來命名兩個完全不同的工作世界。看見領子，這個字的行為就跟著清楚了：它說的是工作在哪裡發生、靠什麼完成。它完全沒有在說誰比較重要。From the word’s history
The name comes from the colour of the dress shirts worn by professional and clerical workers, as against the tough denim and chambray shirts worn by manual workers.
這個名字來自襯衫的顏色：辦公室和事務性工作的人穿白襯衫，體力工作的人穿的是耐磨的丹寧或粗棉工作衫。所以「白領」這個畫面不是比喻，它本來就是在講真的衣服，後來才變成整類工作的代號。

從那件白襯衫長出來的固定說法
同一件白襯衫，換一個問題：如果犯罪的人穿的是這件襯衫，手法會長什麼樣子？
