Re: am I liable
I know it's hard when your an apprentice, but I have always believed that when something is obviously wrong like hooking up speaker wire for a light, don't even ask the lead if he want's you to do that. Just get the right stuff to do the job correctly, as long as you are following the code, and make them stop you. Then you really have a good leg to stand on. If they try to fire you for doing the right thing they are in lots of trouble. Don't be belligerent about it or anything, just do what you know is right and safe. Don't use safety as an excuse not to do something.
If you get told to do something unsafe or wrong, just let them know what you need to do or get to do the job correctly. If they want to try and get you in trouble for doing it right, let them stand before the employment board for wrongful termination. Because when you go for unemployment they will want to know why you were fired. Be honest about it, and it may not seem like it at the time, but things will work out.
When I hit 12 years in the Navy, I stood up against a very unsafe practice that I was being directed to do. I was told that I will do what the Captain of the ship tells me to do. Well I walked of the job, let me say not easy to do in the military. They didn't do anything to me right away and afterwards they tried but they couldn't. Why couldn't they, well the forced someone else to do it the unsafe way, caused better than $1,000,000,000 (Yes 9 zero's) of damage and were extremely lucky they did not kill somebody. So they still tried to say it was my fault for not speaking up strongly enough. Excuse me, walking off a job and flat out telling a senior officer that I won't do it is not very strong? I was hidden in a little hole as a computer information guy for a while and told to keep my mouth shut. Well to this day I do not regret my actions one bit, even though it basically ruined my career.
Anyway I ramble on to much. Stick to safety it will keep you alive and the people you work with and for. Hey, if the company is so great, why would an electrician not have you do it right?
