- Kroger is spending $770 million more this year on wages and benefits for workers.
- It's funding the increase with cost savings, in part from the use of technology, its CFO said.
- Walmart and Home Depot have also recently upped wage spending as US unemployment remains low.
Kroger is latest retailer to say it will spend more this year on worker wages as companies fight to keep employees in a tight labor market.
