BENTONVILLE, Ark. — Walmart plans to cut 1,000 or more jobs, mainly at its headquarters, according to published reports.

The Walmart job cuts are expected to be enacted by the end of the company’s current fiscal year on Jan. 31, according to The Wall Street Journal.

Meanwhile, Bloomberg reported that the retail giant is also making  changes at the store level, cutting about 3,500 salaried store co-manager positions and adding about 1,700 assistant store managers.

The people in those assistant store manager positions, which Bloomberg said are somewhat lower paid, will oversee online orders and other rapidly growing parts of the business. According to Bloomberg, the move is meant to weed out weak performing managers and make the overall company more efficient.

Walmart, the nation’s largest private employer, recently announced that it aims to hike the base pay of entry-level employees in its stores to $11 an hour and pay veteran employees a one-time bonus, expand parental leave and offer financial assistance to employees seeking to adopt children.
