I worked in the film business just out of college. We worked flat rate 14-16 hours days routinely for a nice amount of money. I always saw these guys just standing around doing nothing. I asked who they were and they said, Teamsters. We couldn't even run to the corner in our own vehicle to get bagels. We had to call the Teamster Boss and they would send someone and we would get driven. It was ridiculous. And they got double triple over time starting at 5 pm....they weren't even necessary because I also worked on very efficient non-union shoots with half the people where people could actually drive themselves places. Many of these unions are a just a scam under the premise of fairness..
