They also avoid tax implications by calling the money a "reimbursement" for personal expenses. It is not payment for services rendered- otherwise it is severly below the state and federal minimum wage.
The legal department has a tax preparation group that prepares the taxes for all bethelites every year. That way, no one slips and calls the reimbursement income. The only income that is reported is from "G" jobs. (side work picked up by bethelites to give them some additional income)
