Six months ago, the Communications Workers of America union said that Activision Blizzard allegedly illegally monitors its employees, threatens them and prohibits discussing a number of issues related to working in the company. For example, the salary and working conditions. He also pointed out that the policy regarding social networks is too broad.
The US National Labor Relations Board (NLRB) reviewed the complaint and concluded that it was justified. Now, if Activision Blizzard does not deal with the situation, the NLRB will write its own complaint against the company.
Activision Blizzard in a comment for the Game Developer portal said that all the accusations are false.
