The Wikipedia page on NNESTs is a fairly good intro to the subject with good references: Wiki

If you are a NNEST in Seattle experiencing discrimination at work I would encourage you to contact the Seattle Solidarity Network, an organization that has had a great deal of success fighting employers and landlords who violate the rights of, or otherwise mistreat, their employees or tenants: seasol
Seasol, will work with you to make and secure any demands that you may have, monetary compensation, a position that was terminated unjustly, etc.

If you have been reprimanded or threatened for seeking to better your position through collaboration with your coworkers, whether or not that action has been union related, contact these organizations as well: National Labor Relations Board Industrial Workers of the World

 Here are some Youtube videos of ESL/EFL teachers addressing the issue of discrimination against NNESTs, questions of legitimacy, and comparing them with NESTs in the field (I don't agree with all the opinions expressed here):

Here's a link to a teacher's blog post describing examples of discrimination against NNESTs and non-white teachers witnessed in S. Korea:
http://eltrantsreviewsreflections.wordpress.com/2012/07/22/some-thoughts-and-stories-about-native-speakers-in-south-korea/ The comments here are good too. Many people who read this were teaching in other countries and have chimed in with their own stories.
