The Walton family still has a say on what happens in Walmart, as family members are on the Board of Directors and ultimately the CEO and his leadership report to the Board of Directors. Furthermore, the Walton family still owns a significant amount of stock and subsequently voting power.
The Board is well aware of the management team's vision, strategy, and operating priorities, as well as the company leadership's position on adapting the Walmart culture for the current business environment. The reality is that Walmart is attempting to adjust the ways of working from a tenure/relationship based environment to more of one based on performance and results.
Additionally, based on the analyst presentation yesterday, Walmart is clearly focused on ecommerce in the US as the plan is to only open 25 stores in the next year. That has implications for headcount investments in the brick & mortar areas of the business. In the CEO section of the presentation, there was a clear intent to demonstrate Walmart moving with speed to move to an omnichannel business model with a timeline of significant accomplishments.
This is a tough transition and a bitter pill to swallow for people who have invested a significant portion of their careers in the company. I certainly don't wish being laid off on anyone, and I wish the best of luck for everyone impacted in finding the next leg of their career journey.
