A union leader said Thursday that the proposed merger between Fox News and the UFW Communications Group would “put millions of workers out of work and hurt the future of their careers.”

The deal, which was first reported by The New York Times, would create a combined company with the potential to produce more than 3 million hours of TV programming per year.

Uniforegional Communications President John Harrigan said Thursday in a statement that the merger would be a “tremendous financial risk for our members, and a massive waste of time and resources.”

Unifor is a national federation of labor unions representing the majority of the more than 2.2 million workers in the country.

Its members represent more than 400,000 employees in the U.S. and Canada.

Fox News is the largest cable news network in the United States.

The merger would create the company that would compete with the cable networks and Internet service providers in the cable business, Harrigan added.

It would also create the largest media conglomerate in the world, he said.
