I made some mistakes at my first professional IT job, which was to be expected. Mistakes are supposed to be learning experiences. In my case, they became a career killer, despite being relatively minor.
Things were actually going quite well at this job until this happened. I worked on an executive's Win2k PC at one of my employer's client firms. I got everything working, then noticed that it had an old service pack. So I got permission from my boss to update it to the latest SP, but he urged me to leave the site soon so the client wouldn't get upset about the billable hours.
After the service pack install started running, I thought, "Hey, to save some time, I can let this run and leave. I'll leave a note to the exec telling him to restart the PC after the update has completed. He should be happy about saving some money that way."
Big mistake.
When I got to back to the office, that exec called me telling me that his PC was all messed up. I was surprised because I had tested everything before starting the service pack update, and other PC's with the same configuration and software worked fine with the latest service pack. This exec was livid. Nothing I said would calm him down. Regardless, I was not allowed to perform any work for that client anymore.
My guess is that the exec didn't wait for the service pack install to finish before restarting, as that would cause serious issues. But then I heard from my boss later that this particular exec had some kind of personal problem with me. So then I thought that maybe he screwed up the PC himself as an excuse to get rid of me - I'm not sure.
This incident left me extremely discouraged. Things went downhill from there and I was eventually let go. I have not been able to find a decent IT position since.
It sucks, but what can you do. The only logical reason I can think of for that exec having any problem with me would have been my difficulty communicating effectively (I used to mumble and talk really fast) due to excessive anxiety/nervousness.
I doubt I'll go back to IT. :\
There are many other things I can do anyway - with more respect, less stress, and better pay.
