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.
