Headscratchers / Lonestar

• Mr Mom contains the line "I can go to work until you find another job", in the context of a working man and his stay at home wife swapping places after he loses his job. How is she able to instantly get a job while he needs time to search for one? Is this just a contrivance to make the premise possible? (Unless I'm missing something obvious.)
  • Given they have an infant, it's possible the wife was on maternity leave, and has made arrangements with her job to return while her husband job hunts.
