Lighting Designers are often overbooked and can't be at two gigs at the same time. In these cases they require the support of an assistant LD, a person who can speak on their behalf. This is not an easy job, as the assistant is often asked to make "on the spot" executive decisions on behalf of their boss. Nothing is worse than an LD showing up on site to see that trusses or fixtures were hung in the wrong position. If you agree to be an assistant to an LD, you had better double check everything twice and ask every question, no matter how stupid you think it is. If things have to be moved because you guessed wrong, you didn't support your employer correctly.
