There are numerous stereotypes about the different classes of (white, blue, or even “pink”-collar) workers, typically informed by one’s own status. For example, “For middle-class professionals … blue-collar work is shameful. It is seen as simple, subservient, and alienating. By association, those who perform blue-collar labor are regarded as simple-minded, incompetent, and inferior” (Torlina, 2011). In contrast, many blue-collar workers, such as those working in a trade, see great value and intelligence in their work.
