Maybe they can monitor the trucks with video feeds. Get a union together and demand only one monitor per worker and have laws passed that all trucks must be monitored with video feeds.

I think dock workers used to unload ships and my understanding is, that while not as extreme, they have done something similar. (Not that I see this as the best approach....).

Kind of like freight elevator operators. Utterly pointless trade I discovered while living in New York the last year. You can't bring boxes in through the lobby, only use the union operated freight elevator between designated hours.
