WASHINGTON — Retailers are ramping up hiring for the holiday season, but fewer seasonal employees are expected to be taken on this year to help customers in stores and assemble online orders in warehouses.

E-commerce giant Amazon said Thursday it will hire 250,000 full, part-time and seasonal workers for the crucial shopping period, rounding out a series of announcements made in recent weeks by the country’s top retailers.

Amazon is hiring the same number of employees it did last year, similar to Bath & Body Works and Target, which said in September it planned to bring in roughly 100,000 seasonal employees and offer current employees the option to work extra hours during the holiday shopping period.

Meanwhile, the department store Kohl’s encouraged people to apply for positions but stayed mum on its plans, mirroring Walmart, which said it’s been hiring store associates throughout the year and will tap into its own staff when needed during the busy season.

Others have indicated they will scale back their holiday hiring. Macy’s said it would add more than 31,500 seasonal positions this year across its Macy’s, Bloomingdale’s and Bluemercury stores, as well as its distribution centers. Last year, the company added 38,000.

This year’s demand for seasonal workers comes as economists are watching the U.S. job market for signs of a slowdown. America’s employers added a surprisingly strong 254,000 jobs in September, the latest evidence that the U.S. labor market is still solid enough to support steady hiring and a growing economy.

The holiday shopping period is the busiest time of year for online and brick-and-mortar retailers, some of which have already announced discount events to entice consumers planning to shop early for gifts.

The consulting firm Deloitte forecasts U.S. retail sales will increase 2.3% to 3.3% between November and January and reach a total of $1.59 trillion. EY-Parthenon, the consulting arm of Ernst & Young, forecasts a similar 3% jump in sales during the traditional November-December period.

However, EY Parthenon expects price increases due to inflation to account for a big chunk of that growth, saying real volume sales will only rise 0.5% year-over-year.

Online sales, a growing segment of retail, is expected to increase 8.4% and reach a record $240.8 billion, according to Adobe, which tracks e-commerce transactions.

“At the moment, retailers appear optimistic for a strong holiday shopping season, which is being reflected in the hiring plans of major retailers and warehouses,” said Andy Challenger, senior vice president at the outplacement firm Challenger, Gray & Christmas.

Overall, U.S. retailers are expected to add 520,000 new jobs in the final quarter of this year compared to 564,200 in 2023, according to a report released last month by Challenger, Gray & Christmas. The firm, which analyzes non-seasonally adjusted data from the Bureau of Labor Statistics, says that’s more than the 509,300 seasonal jobs retailers added in 2022. But it represents the second-lowest total since 2009.

Amid the growth in online shopping, the delivery giant UPS said it planned to hire 125,000 seasonal workers for the holiday rush, up from 100,000 last year.

Radial, an e-commerce company that powers deliveries for brands like Calvin Klein and Express, said it intended to hire fewer people but also planned to scale its staff based on real-time demand. That approach allows the company to meet customers’ needs “without overcommitting,” said Billy Peterson, a senior vice president at Radial.

On the buyer side, consumers have been resilient with their spending while also showing signs of stress, with credit-card debt rising and savings rates falling, trends that could weigh on spending in future months.

Retail sales ticked up from July to August, after jumping the most in a year and a half the previous month. At the same time, consumers have been more prudent about their purchases and pushing back against high prices by trading down to store brands or seeking out deals for products.
