Look for the Union Food Label

It's too late for this year, but the site Labor 411 has a useful list of union-made Thanksgiving food products. I imagine they'll have one up for Christmas, too.

Relatedly, the smartphone app buycott allows users to scan products and look up who owns the company. It was designed with consumers who want to avoid buying Koch brothers and Monsanto products in mind, but it can customized by users of any political persuasion. I haven't tried it yet myself, but it's a neat idea that was proposed by Darcy Burner at Netroots Nation 2012. As with mandates on food labels and providing nutritional information, helping customers make informed decisions is a good idea.
