Democratic presidential front-runner Hillary Clinton joined rival Sen. Bernie Sanders (I-Vt.) in positioning herself with workers striking against Verizon on Wednesday.

“Verizon should come back to the bargaining table with a fair offer for their workers,” she said in a statement.

{mosads}She echoed a union claim that “Verizon wants to outsource more and more jobs” and said that the company “should do the right thing and return to negotiations.”

Her comments come hours after around 36,000 workers went on strike following months of fraught contract negotiations. The workers, who have been without a contract since August, are mostly associated with Verizon’s wireline business and are based on the East Coast.

The union says Verizon wants to make cuts to its operation and move jobs overseas. The company says the union is unfairly portraying its demands and using a strike to gum up the negotiation process.

But the strike has gained more political salience with both Democratic candidates backing the workers before the New York primary.

Clinton’s statement came after she was endorsed by a New York chapter of the International Brotherhood of Electrical Workers, which is one of the unions behind the strike.

Sanders has been endorsed by the other union involved, the Communication Workers of America. He joined Verizon workers on a picket line on Wednesday morning, and also backed the strike on Tuesday.
