If you're at dispatch 10 minutes early and CC need someone asap to crew a flight, the first place they look is dispatch. And if you are there early, it does give them an advantage
Sorry that doesn't cut it as a valid example. you would have to speak to Crew Control via phone in the first place. If the flight dispatcher notifies you of a message, then you tell the dispatcher you'll call them in few minutes. It ain't difficult. Crew Controllers aren't on the dispatch floor hunting you down. If they were, no matter if you were sitting in the lounge area, or standing at the counter it would be of no help.
Believe me I detest management as much as you do and I do more than my share. What I also don't like is super militant individuals acting like goons without any concept of how things work. Anyway enough ranting.
