Viejas is such an exciting place to work! Everyone is so friendly and things change every day. Do not be set on your job description because everyone does everything and they have a very team environment there. One thing to note is that Viejas is a sovereign nation and as such they cannot be sued and legally charged for certain things. If you feel that you have been treated unfairly there is NO security for your job.
For example, if you get fired for an "unjust" cause and there is zero documentation for this, it does not matter. You cannot press charges since they are not subject to California laws.
