Pros: never a dull moment and always something different everyday.
Cons: a lot of friendships made via phone, where you may never physically meet that person
As a Unix Administrator at the biggest distribution center Lowe's had at the time in Olin, NC, I was always in demand for help with Spectralink Phones, LRT guns, 4131 terminals, phone system, network issues, etc. I was out on the floor in the distribution fixing issues first hand and in the office as well. Lots of exercise in a distribution size that fits 10 football fields.
At the Support Center, I worked in all aspects of what Lowe's companies receives calls for, which are the following, Hardware, Software, PC and Server. If there was a down store, meaning they lost communications due to a storm, loss of power, etc. whomever was available to take the store immediately did so, sometimes you may be working two calls at once if necessary.
