I've already had one big confrontation a few months ago about a safety issue that I was certainly willing to walk out over. They listened, eventually, but... Why let things get to that point? 

I hate doing it, but I do have the CEOs direct number and I will request a direct meeting with him soon since I don't think that my foreman (who is a good dude, really) is expressing my concerns correctly or as forcefully as I would if I was in his position, especially with my now demand for a raise.
