how do i go about getting a factory job doin things like packaging goods such as pepsi sodas or other supplies?

I’m not sure that there are too many jobs for factory workers with technology being so advanced. Here’s a website called Foodservice Packaging Institute which may provide general info: http://www.fpi.org

Perhaps one can contact pepsi or the other major brands of beverages or such and ask about possible factory positions at one of their plants.

Here’s a website albeit a few years old that talks about how factory workers tend to become displaced more than other workers: http://www.bls.gov/opub/ted/2002/aug/wk4/art01.htm
