I spent the work day walking around campus surveying electrical equipment, usually lights. If I wasn't surveying, I was going directly to locations on campus to complete a work request. I learned a lot about maintenance and lighting during my employment, as well as how important it was for coworkers to get along. It was a very friendly environment, which made working and talking with supervisors very easy. Everyone was approachable, and willing to help out and answer questions. And working in pairs or groups was never a problem.
For me, personally, the hardest part of the job was climbing ladders to change lights, at least early on. I had a fear of heights that lasted a year into the job. Thanks to the work I mostly got over it, but it wasn't easy to climb 8 to 15 feet above ground, or get on a Genie lift and go over 20 feet in the air in a shaky basket, and still operate. But I'm happy I did it, as it improved me physically and mentally.
As for what was the mostly enjoyable part of the job, it's a toss up between all the free food that was shared between my coworkers and I, or the coworkers themselves. I made some great friends and ate some great food while employed there. It was definitely a good experience.
