Job Downgrade And Forced To Leave

[biggestfish]

I was hired 3 months ago at a director level position, which is a newly-created position. The supervisor started to challenge everything of my work and mentioned this position should be a manager level with lower salary since he did not see I am performing at director level. then this week he and a HR person told me they decide to downgrade this position. I chose not to pursue but leave.
Is this a legal activity? I feel it may be a discrimination since I am the only minority in the group.
Is this situation eligible for unemployment insurance benefit?
thanks,
DF
