On TV these wives are usually shown doing the laundry or changing diapers while talking on the phone. Last I saw was a movie with Anne Hathaway doing that job while dating her new boyfriend or working her boring job as a secretary. In the end her boss from her "proper" job takes over the phone customers for her. Sorry if I did offend, judging by all those movies I didn't think it was such a big deal. No idea if it would be a viable job thing (reality is probably different from TV after all).
