>She is a registered nurse, so she can easily get a month off at a time
Tangential, but...a friend of mine is an RN in an ICU who works nights (how he copes with the long hours is beyond me). He's struggled to get a single week off, much less an entire month without quarrel. Turnover is high, they're shortstaffed, etc. What is different about your wife's hospital (maybe there's less pressure and more nurses available in other sections of a hospital)?
She works for Kaiser in the DOU (direct observation unit, ICU stepdown). To get a calendar month off she schedules it almost a year in advance. 2 weeks off she can do with a month notice. A week off usually only requires switching a day or two with another nurse since she only works 3 days a week.
I've known a few medicos/1st responders, including a brother, who do this(take a month/week off, etc). It sounds enviable to most until you see/hear/experience what their 24 hour shift often entails.
