The de-valuation of work by feminization is fully documented in labour history. The reason we talk about pay equity (versus equal pay for the same job) is the valuation or classification of labour or job duties that are viewed a “feminine” or “masculine”. Physical strength, for example, is rated higher than accuracy in data entry and, not surprisingly, physical strength is a stereotypically male trait (unless we’re talking about labour that requires physical strength that is defined as female such as housekeeping or laundry workers, then there are no points or recognition for the physical strength required to do the job).
The easiest examples of the devaluation of work when it is feminized is bank tellers and other clerical work. When clerical work was done almost exclusively by men, the job was considered a skilled and valued profession. As women entered the field (and, importantly, men left it) clerical work was devalued – even as it became more technologically difficult to perform. Likewise, nursing has started to attract more men as it professionalized and started to demand decent remuneration. However, shaking the taboo of a man “doing women’s work” has proven harder than attracting women to work that was historically classified as male. The stigma attached to women’s work is pernicious.
The history of labour is full of examples like those. Social attitudes towards the value of certain work is definitely tied to our perceptions of the maleness or femaleness of certain duties.
