INDIANAPOLIS (AP) — President-elect Donald Trump may have been able to keep 800 jobs at the Carrier furnace factory in Indianapolis but the chief executive of Carrier’s parent company says there will ultimately be fewer jobs at the factory.

In an interview with CNBC, United Technologies chief executive Greg Hayes says a $16 million investment to limit outsourcing will increase automation. And he says “what that ultimately means is there will be fewer jobs.”

Carrier had planned to move the 800 jobs to Mexico to take advantage of the cheaper labor force in that country until Trump persuaded Carrier to keep the jobs in Indianapolis. He has promised lower corporate tax rates to preserve factory jobs inside the United States.
