However, companies that play hardball often grow market share and revenue at the expense of poisoning their brands. And a toxic brand can cause significant damage to a corporation. Is this tradeoff financially worth it, or does playing hardball at the expense of brand image eventually cause more harm than good?

SPRINGFIELD, Mo. -- Walmart’s corporate headquarters in Bentonville, Ark., told its stores across the country to pull and hold a specific lot number of Enfamil baby formula.  The company says it made the move out of an abundance of caution after a 10-day-old infant died from a rare bacterial infection.

Tests are underway on the infant formula that Avery Cornett was being fed, the water used to mix it, and the environmental conditions in which it was mixed.

The product pulled from Walmart’s shelves is Enfamil Newborn formula in 12.5-ounce cans.  The lot number is ZP1K7G.

At least 20 people suffered minor injuries Thursday night inside a crowded Wal-Mart in Porter Ranch after a female customer used pepper spray on other shoppers attending a Black Friday sale, officials said.
At least seven people were examined after being hit with the pepper spray. The 10:10 p.m. incident forced employees to evacuate part of the store, police said.
“This was customer-versus-customer ‘shopping rage,’” said Los Angeles Police Lt. Abel Parga.
He said police were seeking a female suspect. Parga added that it was unclear what prompted the confrontation.
Los Angeles Fire Department officials said they were treating about 10 people with minor injuries at the store, which is on Rinaldi Street near Corbin Avenue in the San Fernando Valley.
Shawn Lenske, a Fire Department spokesman, said the injuries, all minor, were due to “rapid crowd movement.”
No arrests have been made.
