Material 1 has to go through Process A before it can be used.
Process A is not complex, but it requires a handy operator.
Process A is not the focus of my work.
More than 2 years ago, in my first week at this job, I got Material 1 ready to use.
Ten months ago I learned about Process A, from the most experienced person - let's call him BS- so I wouldn't depend on anybody else to get more Material 1.
I was never great at Process A, but for my own use it was enough. I also never had the time to improve it as I only had to do it 3 or 4 times.
BS says I should teach process A to a new person. I reply I don't feel comfortable with that, as I have only done a few times and I think someone more experienced should teach it (I didn't say it clearly, but I meant himself).
He says he will ask person L. I thought Person L was experienced in Processes B and C, which are similar but not the same, but maybe Person L was trained in Process A recently.
Person L comes to my office and asks me details about Process A. Person L has never done Process A.
I am teaching Process A to the new person and to Person L. Wish me luck...
