The company that runs the Olive Garden chain is raising pay for its workers and handing out one-time bonuses, a sign of optimism from the kind of casual sit-down restaurant that has been devastated by the pandemic. Darden Restaurants said every hourly restaurant worker will earn at least $10 per hour including tips as of Monday. That will rise to $11 per hour in 2022 and $12 per hour in 2023. The company on Thursday reported a surprisingly strong quarter and the pay hikes signal both confidence about an economic recovery and potentially increased competition for workers as the U.S. emerges from the pandemic.
