In an experiment apparently aimed at keeping down the cost of health-care reform, Orlando-based Darden Restaurants has stopped offering full-time schedules to many hourly workers in at least a few Olive Gardens, Red Lobsters and LongHorn Steakhouses.

Darden said the test is taking place in "a select number" of restaurants in four markets, including Central Florida, but would not give details. The company said there has been no decision made about expanding it.
