i am not sure about fab10, but now it is 100% micron owned, as they have purchased it over from the 50:50 ownership of intel:micron, so i would assume they will follow similar micron policies in terms of compensation and benefits.

the company has been making losses after losses since 2nd half of 2011, and recently i have been hearing people getting promotions without increment, compensation not being adjusted to a point that fresh grads that joins have a higher basic than someone of 3 yrs exp, etc. based on personal experience, the technical work is definitely engaging, not some paperboy with an engineer title, but the compensation level will start to become a big consideration as time goes by
