A worker is asking us for a loan: How can we set up a legal repayment plan?

Q. An employee wants to borrow $2,000 from the company to cover a family emergency, and we’re willing to make the loan. How should we structure the loan and repayment terms so we can deduct a certain amount from the employee’s bimonthly paycheck? We also want to be able to deduct the balance of the loan from the employee’s final paycheck in the event he is terminated before completely repaying the loan.
