U.S. ATC here. I don't think you know what you're talking about: the union is doing nothing for our salaries. The union has no say on where new graduates get placed.
Our union is a joke. They send emails saying they're "monitoring the situation" instead of talking with the media stating our case for better working conditions.
Our salaries have not kept up with the industry. Do not use this to try to push an anti-union agenda.
