NJLUV-
Just a few corrections:
It's a "Load-in" not a "Move in"
Also, A flyman is required because all of the lighting instruments (among other things) are in the air above the stage. God forbid something goes wrong and the electrics need to come down and there is no one qualified in the theater to operate the Flies.
FlyingMonkey:
I think your comparison to the Supermarket industry shows your ignorance. The Producers hold all the cards in showbusiness. The ratio of labor to jobs is tipped heavily in favor of management, making Unions and the rights and protection thy procure protect, and provide so much more important (I am not implying that supermarket employees deserve less).
When you have a surplus of labor, and a lack of Jobs, it is easy for management to take advantage. When you eliminate unions, slowly but surely you will see things like healthcare, pension, and minimum salaries fall by the wayside. It then becomes a profession that ceases to be secure. Who wants that?
Other than that, did you enjoy the play Mrs Lincoln?
