"As part of ongoing talent management, many store operating divisions are evaluating middle management roles and team structures with an eye toward keeping resources close to the customer," a Kroger spokesperson said in an e-mailed statement.

Over the past couple of years, Kroger has been expanding home delivery, curbside pickup and self-checkout services, apart from investing heavily in technology such as its recent deal with UK-based Ocado Group to speed up its delivery operations with robot-operated warehouses.

The spokesperson said store divisions operate independently but Kroger is taking steps to ensure it has the right talent in the right store leadership positions.
