The deal will save only about half of the 2,100 jobs that Carrier said in February it would cut in closing two Indiana plants.

The manufacturer said the “forces of globalization will continue to require solutions for the long-term competitiveness of the U.S. and of American workers moving forward.”

Trump’s intervention in the Carrier case raises the question of whether he will step in whenever manufacturing jobs are lost. By negotiating a deal with one company, Trump could come under pressure to do similar deals with other companies, said Alex Major, a partner at law firm McCarter & English.

That could result in what he called “a revolving door of trick or treaters at the White House,” looking for handouts as they threaten to move jobs overseas.

Aside from Carrier, Indiana businesses have outsourced at least 3,660 jobs since the middle of last year, Labor Department figures show.

Senator Joe Donnelly, an Indiana Democrat, noted that there are two other companies closing two Indiana factories, including one a mile from the Carrier plant in Indianapolis that is expected to move to Mexico.

OTHER COMPANIES IN CROSSHAIRS

Oreo cookie maker Mondelez International, another company Trump has accused of shipping jobs overseas, told Reuters it has not heard from Trump since the election.

Apple Inc (AAPL.O), another Trump target on the campaign trail, which makes the vast bulk of its electronics in Asia, has made an attempt to reach out to the president-elect.

Trump told the New York Times he had received a call from Apple CEO Tim Cook. He said he told Cook he would like to see Apple build “a big plant in the United States," according to the Times report, with the help of incentives and a “very large tax cut for corporations.”

Apple did not answer questions about the call between Trump and Cook, but it did note that it employs 80,000 people directly in the United States.

Carrier declined to disclose the exact size of the incentives for keeping jobs in the state.

"It's a modest state tax credit utilizing existing state tax tools; nothing new," an Indiana state official told Reuters. "It would be the same kind of package that would be considered for any other company that would come in," said the official, who spoke on condition of anonymity because the incentives have not yet been made public.

Carrier still plans to close a factory in Huntington, Indiana, that employs 700 people making controls for heating, cooling and refrigeration and move the jobs to Mexico by 2018.
