I worked for Sears for a while as a service tech in their electronics department. I also ended up working on some of the white goods appliances as well. Sears has one of the worst run service departments in the industry. It's not the fault of the techs, some of which have been there for years. It is a fault of the way it is managed. They have an automated computer system that is supposed to route calls based on the proximity to each other, to minimize travel time. Management however likes to re-arrange the service calls and re-schedule after the technicians get them and call the customers up to tell them they are on the way. If there was some reason that a return trip needed to be made...for parts or something, the original technician that ran the call rarely ever got the call for the return trip.
We rarely EVER got enough time allocated by the computer to do the job correctly. If the computer gave us less than 5 calls a day, they would re-schedule the calls for another day, and you sat at home that day, and didn't get paid! The problem was that getting 5 electronics calls done in a day was quite a chore, especially once management mettled with the computer routing system and made you end up travling over 200 miles that day! I would start the days at 6 AM, and wouldn't get home till 8PM that night sometimes
Sears also doesn't provide the technician with the proper literature to properly perform the job. We had no parts lists, schematics, assembly diagrams or anything...we were operating on blind intuition. Getting the proper tools to get the job done was a pain too.
Parts were a really bad issue. I carried around a van load of parts that were not even really needed. The parts that were needed we ended up having wait over 4-6 weeks to come in.
I only tolerated that place for about a year, and then got a job working for a professional audiovisual company. I'm now working on TV editing and studio equipment, professional sound and recording gear, as well as video confrencing systems, and even a little bit of networking non-computer devices (like white goods and robotics). It's a small local company that is a total polar opposite as Sears, and does everything right that they don't do! Stress is practially non-existant, and the customers love our work!
