Hello, I want to start by saying I still have a lot to learn and don't want to cause trouble, but my foreman's requests bug me. He wants us to support light fixtures off 3/4 EMT, which I know isn't allowed, they are the type that need all thread so he wants us to put struts with strut straps hanging off the EMT with spring nuts to thread the all thread into. I am worried if a higher up comes I would get blamed. Should I tell him to kick rocks and order the correct material so this doesn't bite me in the ass? What would you do?
