AI is meant to help workers do their jobs.

Some Walmart employees say they're the ones providing assistance in the relationship.

Walmart's massive bet on AI includes equipping in-store workers with a suite of tools to make them more efficient.

But in some cases, workers are finding themselves frequently correcting mistakes and training the tech, writes BI's Dominick Reuter .

As the largest US private-sector employer, it's a great example of the challenges that can arise when trying to effectively get AI tools used by your staff at a massive scale.

Workers told Dominick the tools don't factor in complications that could arise from a simple assignment.

Restocking an aisle involves more than putting merchandise on a shelf.

You might first need to clean up a mess or remove items past their expiration dates.

In other cases, the tool inadvertently creates more work.

Spark, Walmart's delivery service, updated a feature that helps drivers navigate stores when picking up items.

But tracking workers' real-time locations ended up wasting more of their time , sometimes prompting them to pick up items like ice or frozen foods first.

Walmart seems comfortable with hiccups being part of the process.
