Sounds like a lot of industries where the employees are run into the ground. I've worked with people that guarded all of their knowledge, unwilling to share the simplest bits that would make a task turn out better. Never understood that.
The only manufacturing facility I have toured was STI Guns in Georgetown, TX (now Staccato) and virtually everything there was done in CNC machining centers. Beyond the CNC, the rest was hand fitting of competition pistols. It's a very nice facility. Other than that, I've only been in job shops. One shop I visited in New Mexico's oil country was remarkably clean. The owner told me that he had one employee whose only job was to keep the machines and shop clean. There wasn't a stray chip to be seen anywhere.
Oh boy, I could tell you stories.
I had a guy who absolutely hated me for no discernable reason, simply the most
Narcissistic Sycophant you would ever meet.
He told me he would never teach me anything and I would flunk out of the program and lose my job. This was in my first year. Nice guy EH?
FF 25yrs later and he's my group leader.
He would come at me with an attitude..."DO THIS!" Almost always a **** job.
And I would just look him in the eye and say, "Cant, you never showed me how and I flunked out.".....The look on his face.....
We went round and round with this until I got called into HR one day. All I had to do to defend myself was simply ask "What kind of leader cant get his guys to work for him?"
Now all along I was doing good work, some would say exceptional work for engineering, and turning out whatever complicated contraption they wanted. That go to the point where they would just come to me with a problem or idea, buy me the tools and materials and I would give them better than they envisioned.
So when it got to the point of going in front of HR, I wasn't the one with egg on my face. Im pretty sure me still working here after he has retired tweaked his nose a little.
**** em! But do it gently and with a smile on your face so they dont even know you're doing it.
