For 26 years I worked in the Data Center of a local School District. We processed everything from paychecks to report cards, and everything in between. My main function was writing programming code (I'm talking old school IBM languages - mostly RPGIII with a little COBOL thrown in for the business / accounting department. But I also filled in as data entry, running the printers and system backup when needed. It was a fun, but sometimes stressful job. (Think system crash).
Now I run an eBay store which is nice because I can hide all my listing when I'm out of town, list as much or as little as I want. Total situational control.
