I have worked less than full time hours for years and years. It gives me the rewards of working, financial benefits, but limits my exposure.
Per diem work means I never have to join a committee, am in charge only in emergencies, and I get to enjoy meaningful work out in the world, but only one or two days at week. I went per diem for childcare reasons. The kids are grown, but I like my freedom too much.
I am lucky to work in a unit that while busy at times, has a reasonable workload, a free charge nurse with no patient assignment, a transport nurse for ICU patients, IV team, a manager who cares and strong coworkers. I haven't missed a lunch break in years.
Less than full time hours in a quality unit, a life outside of work and reasonable expectations have benefitted me.
