Amazon plans to hire 100,000 over the next 18 months

Amazon plans to hire 100,000 full time workers over the next 18 months, highlighting its ambitious expansion plans -- and the sharp contrast the e-commerce powerhouse strikes against traditional brick-and-mortar retailers, many of which are cutting jobs and closing stores.

Amazon has long been known for investing the money it makes back into its businesses, and it's doing that with a vengeance. The new hires will largely support new Amazon fulfillment centers in states such as Texas and California, expanded delivery capabilities and its money-minting Amazon Web Services cloud computing business.

The numbers are generally in line with Amazon's past hiring plans. Amazon, which had a total of 306,800 full-time and part-time employees globally at the end of September, hired a total of 123,700 globally during the 15 months ended in September, according to quarterly filings.

AMAZON HITS THE GAS

Amazon said Thursday its U.S. workforce has grown from 30,000 in 2011 to over 180,000 at the end of 2016. By comparison, Walmart -- the world's largest retailer -- employs about 2.4 million people worldwide, including 1.5 million workers in the U.S.

Baird analyst Colin Sebastian said the announcement shows that Amazon's hiring appears to be accelerating.

"We view this announcement positively in terms of the current trajectory of Amazon's businesses, as well as management's confidence in the long-term outlook," he said. "The hiring is consistent with our view that Amazon will continue to invest aggressively in its retail, media, technology and logistics businesses."

TRUMP OR NO TRUMP?

The news comes a month after President-elect Donald Trump met with tech leaders, including Amazon founder Jeff Bezos. Throughout the presidential election campaign Trump and Bezos clashed after Trump attacked Bezos and The Washington Post, which Bezos owns. But they appeared to make nice when Bezos attended the meeting in December.

Sean Spicer, the incoming White House press secretary, noted in a call with reporters on Thursday that Amazon made the announcement after the meeting, when Trump urged tech leaders to keep jobs in the U.S.

Spicer said that Trump was "pleased to play a role" in the job gains. Amazon did not immediately respond to a request to comment on what role, if any, Trump had in the jobs announcement.

Baird's Sebastian downplayed the politics factor, noting only that the online retailer may have deployed some "political capital" in the timing and details of its announcement.

"We suspect there is little, if any, shift of employment at Amazon from international locations to the U.S.," he said. "Moreover, we expect the pace of hiring internationally to accelerate as well."

MEANWHILE, BACK AT THE STORE

Things are much less rosy at traditional brick-and-mortar retailers. Last week, the Limited said it would close all its stores and Macy's moved forward with plans to close 68 stores and said it will cut more than 10,000 jobs. There have been unconfirmed reports Walmart is also planning layoffs.

"The move from bricks to clicks is causing major disruption in the retail industry," said economist Diane Swonk.
