Shifts are scheduled such that you work your full shift (4-8 hours) whether or not you have clients. This is nice because you can count on a consistent paycheck, but not so nice because you're paid minimally.
1) opening duties/cleaning tasks
2) reviewing schedule and client charts for the day
3) train clients (half hour sessions)
4) Clean up/complete monthly tasks during down time
5) Complete closing/mid-shift duties and prepare client cards for next trainer
