My production is a topic of debate with my on car and center manager from time to time. When they brought these letter packs out I said I was not interested in doing it if there was not a way to code it out.
You also have to really know a customer is already supportive of the legislation anyway before we just stumble in with a request like this. I think its like playing with dynamite. Most people have either a strong pro or anti union view. Very little middle ground. Most business owners I know don't support union friendly views even if they like me personally. UPS has done a good job of villifying the Teamsters over the years and now to ask it's customers to sign on to this seems like double talk. A lot of business owners and people in general believe that the "union" is what went wrong in Detroit, even though it was the companies who decided year after year to make gas hogs that just finally stopped selling.
I don't think this campaign will be very effective unfortunately.
