Shouldn't an employee get the Manager to do a performance review before a pay raise happens?

One of my coworkers keeps bragging about how he got a pay raise. This was all done by him talking to my boss's boss. My boss keeps complaining that it's not right because had he given him a performance review, he wouldn't have granted him a pay raise. That's not fair in my opinion either because I don't know my boss's boss that well to call him up and ask him for a pay raise, therefore any pay raises I get will be based on a performance review. What are the rules about this?

Basically, there are none. Every business owner has the right to set the policy as to how people are paid and how much. Unless there's been a violation of a union contract or you can prove discrimination then the only option you have is to call you're bosses boss and attempt to get a raise as well. If your boss likes your work then he may back you up.
