Walmart Stores is hiring 55,000 seasonal workers and is elevating 70,000 more to part- or full-time positions as the holiday season ramps up.

The world's largest retailer said Monday that 35,000 temporary workers will become part-time and 35,000 part-time workers will gain full-time jobs.

The shift means that Walmart will be offering more of its workers benefits. That's significant because Walmart has been a target of attacks by labor groups for what they say are skimpy wages and benefits.

Last season, Walmart hired 50,000 workers and said it would offer more hours in general to its existing employees.
