Wow, I clicked on the SEIU link and the first thing that pops up is a photo of three VERY ugly, defiant, angry looking people. I would never want to join an organization that has members that look like that!
BTW, I used to work in a healthcare facility (in management) that was targeted for unionizing by the SEIU. Those thugs would harass our employees at home and at work on a daily basis. One poor girl had to call the cops to have them hauled away from her apartment doorstep after they started screaming and threatening her. SEIU is made of the worst kind of street level thugs.
