President-elect Donald Trump took to Twitter to personally attack union members at Carrier for setting the record straight on the number of jobs that are actually being saved at the company. Trump claimed that 1,100 jobs were being saved, but it’s only 800; and 550 jobs are still being shipped to Mexico.

Now, Chuck Jones, the president of the United Steelworkers local that represents Carrier workers, is getting threatening calls for speaking out and telling the truth.

Sign the solidarity card now to tell Carrier workers that you’ve got their backs.
