It's all about expectations that were set when someone started.

If one was given the expectation that they'd commute to New York for reserve for three months before holding a line there, and then they ended up commuting to New York for reserve for eight months, then they probably would be unhappy.

If one was given the expectation that they'd sit reserve in base at home, and then they ended up sitting reserve in base at home, then they probably would be happier.
