The idea behind this union of unions is to use the collective buying power of unions across the US in order to offer a variety of high quality, discounted products and services exclusively to working families. Included in this program are all sorts of benefits, like credit, insurance deals, health insurance, shopping discounts, auto advantages and more.
In order to take advantage of the benefits you must be affiliated to some union that is in turn affiliated to Union plus, so you should probably check that out first. At this site you will also be able to consult the Union plus library and archives for press releases and educational material, both in English and in Spanish when the translation is available.
