Mentoring sometimes works and sometimes it doesn't !!.
Years ago, I was working in a Western Canada bank running PICK reports. The system was running slower and slower and needed maintenance. My boss would not pay for the $7000 System Engineers course, so with the help of a friend in the local dealers office, I taught myself systems maintenance on their test system during the evenings. It paid off, since my salary doubled in two years
Fast foward to last year. For 13 years I had worked in a large TO based food processor supporting the Servers, Users and the very critical DOS based dealer handheld order system.
It wasn't that complex, 4 batch files and a couple of REXX programs.
One day, my boss hired a new MCSE and a lady with a degree in programming and asked me to "teach" them the HH system, in case I "got hit by a bus".
After three weeks, they were finally able to descibe what each line did in the programs.
Two weeks later, I was "let go". My boss told me that he could get two for the price of one !!
I find now that I am either UNDER or OVER qualified for positions and I'm told over and over, that it's easier to reload systems than actually troubleshoot them.
Tis fun out there ...
