I worked in data processing, and the friday before a major change in computer systems, I was laid off.. My changes affected the way information was accessed and updated. Over the weekend I was offered a position with a nice pay raise. Well that Monday when the computer systems were brought up, nothing worked correctly because computer programs that I changed were not brought into the computer per the instructions that I had written. In addition they had not backed up critical data, to back things out, so they were between a rock and a hard place.
My previous employer called me up and wanted me to come back and get the computer systems up and running. I explained that I had accepted employment elsewhere and would not change my decision. My previous employer then offered me a bonus of 1/4 my annual salary if I would come in, correct the issues. I was scheduled to start my new job a week later, so I said draw up a contract, and I will be in.
It took me approximately 16 hours to straighten things out and laughed my way to the bank in order to cash that check.
