(Reuters) - "Call of Duty" maker Activision Blizzard Inc has been accused by a union of illegally firing two video game testers for using "strong language" in a protest of a new company policy that limits remote work.

The Communication Workers of America (CWA) said it filed a complaint with the U.S. National Labor Relations Board on Tuesday seeking to have the workers reinstated.
