My first salaried job was also my first proper IT job and I was a "junior technician" ... the only other member of IT staff was my supervisor who had been a secretary that got a 1 week sysadmin course and knew very little.
The server room was a complete rat's nest and I resolved to sort it out. It was all going very well until I tripped over the loose SCSI 3 cable between the AIX server and it's raid array. While it was in use.
It took me 2 days to restore everything from tape. My supervisor was completely useless.
A few months later I was "made redundant", leaving behind me everything working perfectly and a super tidy server room. I got calls from the company asking for help for the following 6 months, which I politely declined.
Yeah, I got laid off twice more before switching careers. Both times they wanted me to come back and fix stuff after letting me go.
It goes hand in hand with the "if someone works hard, they should be given more work as a reward" line of thinking.
