There aren’t many movies that qualify as appropriate viewing on Labor Day. One that does is Salt of the Earth, the story of a 1950s strike at a zinc mine in New Mexico that features a clash between the company and the mostly Mexican-American miners. It also features early feminist union supporters in action. You can see it on YouTube at https://www.youtube.com/watch?v=n3VPWmqaOb4. A PNLHA connection: Oregon trustee Ron Verzuh has made a short documentary film called Remembering Salt that is also available on YouTube at https://www.youtube.com/watch?v=YQdV9B8Zj-c.
