The tutor team is awesome and really watch out for each other. There are always tutors willing to sub (for example on holidays).
Pay the tutoring staff more and offer full-time positions for tutoring staff. Many tutors can only work up to 10 hours a week with no health benefits.
There is no ability to promote as a tutor. You must study your lesson material (vocabulary words, concepts) ahead of time to be prepared for tutor sessions. Up to six learners can be in your sessions - which can be stressful. Also Rosetta Stone is open 24/7 so no holidays off, or no pay.
