Oh...they know! Lol! My dispatcher is actually a friend of mine. I knew him before he moved over to being a dispatcher. He irritates me sometimes, but a lot of the times that I get a bad load, its due to the load planners, not him. He can only dispatch the loads he is given to him by the load planners. I vent TO him, not AT him.
He's a good guy and he gets frustrated at them as well. Because he's a company employee, he gets to go out on "ride-alongs" with me for a week every year, so he can see what its like from a drivers perspective. And 1 week out of the year, I sit with him in Des Moines, IA to get a feel for his job. My company offered me a job as a dispatcher out of our Joplin, MO office, but its just not for me. Too much office politics. Plus that'd be a 1.75 hour drive to and from the house.
