One day the line was down due to a switch. It didn't take much to determine which switch kept it down. When the electrician arrived, I told him which switch was holding us out.
He immediately moved to within about 3" of my face. His face was very, very ruddy like an alcoholics would be. We were about equal in height. His breath and body wreaked of alcohol. I moved back a couple of steps. We continued to talk and he moved towards me again with about 3" to spare again. I backed up again. This continued until I was completely backed into the assembly line. Thankfully it was down.
He smelled so much and so badly of alcohol I could hardly stand to talk to him. Every pore of his body wreaked with alcohol.
Once backed into the line, I was trapped. The electrician would not relent until he had said his piece. He was angry that I had told him which switch was keeping us down. He didn't want me telling him what to do. After all, in his estimation, I didn't know how to troubleshoot a switch.
Once I apologized for upsetting him, he moved away to an acceptable distance. I had asked him to move out of my personal space prior to the apology but he refused. He insisted on making a point. What he didn't realize was his aggressiveness in doing so. I could have turned him in to management but didn't. That was his livelihood and his treatment of me wasn't that big a deal.
That apology was all he needed. His attitude shifted dramatically and he became quite congenial. It was almost like watching Dr. Hyde and Mr. Jekyll.
I didn't know what else to do other than let him air his grievances towards me and apologize for my behavior. He never did apologize but I am only responsible for myself.
