Description
Two young men - blue collar workers wearing work clothes and bright yellow protective headwear hardhat safety helmets - are working together; straining while carrying a very heavy cardboard box they are unloading from the back of an open truck trailer parked at a concrete loading dock. The man on the right is carrying the load with better technique - leveraging muscles in his whole body to help his straight arms. The technique and positioning of the man on the left is not ideal because he's carrying mostly with his arms rather than his whole body - potentially causing injury by putting undue strain on his arm, shoulder and back muscles.
