Corporate employees at Walmart and Sam's Club, its warehouse chain, will be reclassified into fewer groups of possible titles and in some cases, pay changes will go into effect, starting in November. Stock option awards to the staff will stay the same or even increase in many cases. About 4% of the staff will see a decrease in stock-option awards to ensure compensation is aligned across geographies, Walmart said. Staff who will see a reduction in stock options will receive a stock grant to account for the change. The change is "good compensation hygiene," and ensures Walmart is "appropriately rewarding similar levels of work," The Wall Street Journal, which first reported the news, quoted Walmart's head of global total rewards Kim Lupo as saying. Earlier this month, Walmart changed the hourly starting wage structure for entry-level store workers.
