Amazon.com Inc. (NSDQ: AMZN) announced it will add 100,000 seasonal positions across its US network of fulfillment and sortation centers this holiday season — up 25% from 80,000 seasonal positions added last year — in order to meet an increase in customer demand. The company has also hired more than 25,000 full-time employees since August to meet customer demand and prepare for the 2015 holiday season.

Amazon has more than 90,000 full-time employees across its more than 50 fulfillment centers and 20 sortation centers in the US. Throughout the year on average, about 90% of associates across the company’s US fulfillment network are regular, full-time employees, the company reports.

“Following last year’s holiday season, tens of thousands of seasonal employees found regular, full-time roles with Amazon,” said Mike Roth, Amazon’s VP of North America operations. “We’re excited to grow our team by finding great talent through our seasonal hiring efforts in addition to creating new full-time jobs that offer comprehensive benefits starting on day one.”

Amazon’s plans differ from a recent survey released by job portal Snagajob, which found employers expect to hire a similar number of temporary workers this holiday season. The National Retail Federation also reported it expects retailers to hire between 700,000 and 750,000 seasonal workers this holiday season, in line with last year’s 714,000 new holiday positions.

Several firms previously announced seasonal hiring plans for the upcoming season that are similar to last year’s:

• UPS: Between 90,000 and 95,000
• Wal-Mart Stores Inc.: 60,000
• Macy’s Inc.: 85,000
• Sports Authority: 3,500

However, FedEx Corp. expects to add more than 55,000 seasonal workers throughout its network this holiday season, up from 50,000 seasonal workers the Memphis, Tenn., company said it would hire last holiday season.

On the flip side, Toys ‘R’ Us plans to hire 40,000 seasonal employees this holiday season at its stores and distribution centers nationwide, down from last year’s 45,000 additional seasonal employees.
