Ironically, this occurred while I was reading this blog:
I work as a chemical engineer in a chemical plant, I started in the last six months. We were missing 3,000 KG (6,600 lbs) as 40,000 KG moved from a vessel to a tanker truck, which is *very* significant and a problem! I checked the warehouse, the computer data, did some rough calculations for how much would have had to spill out of the tanker truck to account for what happened. I spoke with over 15 people to see what had happened. Everything was perfect and in order, so nothing was resolved. I reported at our main meeting that we had the missing material and that no one was at fault, but it was inappropriate to list in extensive detail my investigatory work.
After the meeting, this other new hire engineer (male) asked for specifics of my investigation. Before I could go on, he started to explain how to subtract the two weights, one from the vessel and one from the truck, to get my 3,000 KG figure… which I already had… And had referenced multiple times. He was ‘teaching’ me basic math in front of my other coworkers.
I had a sheet with the figures from my further investigation in my hand, so I just cut him off and tried to make him feel like the idiot that he was.
