I got a pretty substantial raise from taking a long sought after promotion. I had basically been doing the work for close to 2 years without officially getting the job title after repeated broken promises from my boss. It was beginning to feel like they were just going to take advantage as long as I was willing to do the extra work without the accompanying raises. After telling my boss in my yearly evaluation that I needed him to tell me the date this promotion was coming or alternatively he would need to stop having me take on the extra responsibility, he came through with about a $15k per year bump in pay and the job title. I wish I had spoken up sooner!
