While looking for information about Thor Industries, I ran across this site:
http://en.wikipedia.org/wiki/Thor_Industries
I'll be the first to acknowledge that wikipedia is not the best quality reference site, but I found the following to be very interesting:
Like several other firms in the industry,
Thor offers employee incentives based on productivity, with reductions in bonuses based on warranty work. Thor encourages employees to be actively involved in community programs and Thor executives serve on the boards of numerous civic organizations.
That policy could go either way, it COULD enhance quality on the production line, or it COULD increase warranty claim rejections around "bonus time"
I found it interesting that a comment such as that was out there for anyone to read.
