Tired

I am thinking about a career change. I am tired of the constant arguing and debating with coworkers about how things should be done. I have one coworker in particular who is driving me crazy well not just me everyone else to but we will leave that for another day. Everything no mater how insignificant has to be debated for example the other day we had a piece of equipment fail. I looked it over and discovered the problem was a bad relay something that would have taken me about two minutes to fix. I went back into the workshop to get a new relay and my coworker is waiting with the typical question “so what’s wrong” I say a relay needs to be replaced and this leads into the next question “Why?” ah duh because this one is bad and needs to be replaced. Followed by “But why are you sure it’s a relay maybe it’s a bad wire or the system is not working right” from here we go into an hour long discussion where I explain over and over again why it’s a bad relay and not all the other suggested problems and explain until I’m blue in the face that sometimes these things happen the relay just went nothing caused it to go it was probably just faulty. I get frustrated to the point where I just leave with a new relay in hand and go replace the bad one. Replacing the relay solves the problem and all is well again. I return to the CER (central equipment room for those who don’t know) to find my coworker going the system trying to find the problem because “It can’t be relay” I say what’s up and in return get the following “just trying to find the problem” I reply I changed the relay everything if working now and just walk away shaking my head and wondering what will the next debate be about. I am tired of this I spent an hour explaining the problem for that hour the system was down I could have had it fixed in under two minutes but that would have been too easy. Why cant we just fix a problem when it arises why do we have to pick it to death first?
