IT is definitely a job that has to know how to pick up heavy objects. I have a friend who was working as a consultant configuring corporate telephony systems. One time, he showed up to an install that was running a bit behind schedule. He stepped in to help finish the server room set up and ended up permanently damaging his back.
Yeah, I worked for an American company in Europe, but I asked because at least the labor laws in my country required they showed me box lifting training too.
