Favoritism in the Workplace

I was curious to know as to whether anybody had suffered any discrimination in their place of work. I wonder what kinds of discrimination occur more regularly. Do people get better deals, more classes, fewer classes, and better earners?

I also wondered if bigger employers or types of employers discriminated more. Was the discrimination nationality, skin color, looks or gender based? Does anyone feel there is discrimination in the workplace here?

I think you have to earn your corn here. I was wondering if people think you just need looks to get by.
