Walmart Bay Area layoffs – more than just rumors?

Hearing a lot of chatter about these 400 layoffs at Walmart in the Bay Area, specifically San Bruno. The news articles are pretty vague, just saying "corporate roles" and "restructuring." Feels like the usual corporate speak to soften the blow. Anyone working there or know someone who was impacted? I'm trying to get a clearer picture of what exactly happened. Was it a specific department, or more widespread? It's concerning to see this happen, especially with a company as big as Walmart. They reported huge profits not too long ago. Makes you wonder what the real drivers are behind these cuts. Is it just cost-cutting, or are they shifting focus away from certain operations in the Bay Area? Any insider info would be super helpful for those of us watching the retail sector.
