Electronics Forum | Wed Dec 05 10:42:39 EST 2012 | Juggalo

I personally agree with that, but whenever I try to enforce safety the employees run to the owner and then I am made out to be a bully. I honestly believe I work in a different world than the rest of you. I am guessing in my case its best to just lea
