Enforcing Sales Quotas

Q. As a large retail business, we employ several “demo staffers” who present products to shoppers in the hope they'll buy them. Recently, given economic pressures, we've had to put increasing pressure on our demo staff to increase sales up to 200 percent. If a demo staffer doesn't meet the new goal, can we terminate her? Do these workers have legal recourse should they be fired? —T.P., California
