An ad campaign highlighting the fact that the pay is better at Walmart appears to have hit home at Target. The chain, which has been under pressure from labor groups and is facing more competition for low-waged workers, has announced that the minimum wage at all its stores will be raised to $9 an hour starting next month, reports the Wall Street Journal. The advocacy group UltraViolet recently ran an ad campaign that told people near the chain's stores: "Did you know there's a Walmart near you that pays higher minimum wage than Target?" reports Reuters. Target says many of its workers—especially in places like North Dakota and New York—already made more than $9. (Walmart workers say that to earn a good living, they need more hours as well as higher pay.)
