I came across this on reddit. It was posted 9 months ago, but gives great insight about how awful things are...
"I work at Sears, as a Backroom Associate. The PMT (Preventative Maintenance Technician) position opened up. The day the old PMT worker put his two week notice in, my boss approached me asking if I would like the job. Knowing that the pay was better than my current position's, I was excited and instantly told him yes. The following day they started training me for the position. This went on for about a week or so, they announced that there would be a meeting at the end of the month. Well, I attended the meeting only to be introduced to the new PMT worker! I couldn't believe it, they gave me the job and then took it away just like that. Ever since then, there has been no mention of the incident. They handled the entire situation in such a horrible manner, I guess that's why Sears is one of the top ten worst places to work at. F### Sears!"
