Well the spa I work at is new (about 6 mo. old), and not by any means large... we have just four treatment rooms ATM, but our training and our staff meetings are unpaid as well.
(Although they did provide lunch during the days of our training.)
You might search RelaxandRejuvenate's posts for more information about what's normal in the big spa biz.
