I was a dispatcher at EGCC for nine months with Servisair, it's hard work and you dont get too much time to chat to flight crew but you can make some contacts.
However I was only a dispatcher for nine months as I was lucky to get a job on the 737 at EGCC with one of the airlines I dispatched, I brought it up in the interview and explained my role and that I thought it would be helpful on the flight deck to know about some of the problems that you can experiance from the other side and that it would help me in the long run to have a greater understand of the entire turn round procedure.
I think it personally helped me, and you can make some good friends and have a good time at work beats being in an office with a pc and phone.
