Late last year, Target started giving detailed guidance to store employees about how to act. The 10-4 rule, as the company calls it, directs them to smile, make eye contact and wave when a shopper comes within 10 feet/3meter. If they come within four, they should engage verbally by asking whether they need help or how their day is going. Starting this summer, the retailer will start enforcing a new mandate - this one about how employees should dress: blue-colored denim or khakis with plain red shirts. No more of this pink or maroon business, and large logos and graphics are forbidden- unless worn under a company vest. Store leaders will have to trade in their shorts for pants. The company is providing a free t-shirt and additional discounts to help employees meet the requirements.
