Me and some coworkers are thinking about trying to group negotiate a raise.

I am not sure if this is the right place for this post. But I currently work for a state based credit union, and there a several coworkers and myself that are not happy with our current hourly wages. We are thinking about as a group to renegotiate our wages. Thoughts on the subject? Any experiences? Just trying to get some feedback if this is something worth the attempt.
