Some of you obviously don't live in the real world. When you quit, you show the employer that you aren't as loyal as you would like to believe. You can't swing a stick without hitting a dozen people who would be more qualified to take the job. The minute you start thinking "they can't get rid of me", you'd better have your resume updated. I've seen incompetent but difficult to fire employees get shown the door just for spite. Reapplying is the most ignorant advice possible. If they wanted her, they would have already offered the money they're willing to pay. You will lose if this is your strategy to get a raise.

Well apparently the company could have afforded the raise.

if you plan on insulting, spell and punctuate correctly.

you never know why they might need the money. they can be under threay by the IRS or they can have a bill which they cannot pay off without a raise. so please don't bitch in the comments.
