You might also temporarily benefit if others on your team start quitting before you.
Management might throw some short-term things your way if you smile politely and play along until you have the next position lined up. The trick is to NOT LET THEM KNOW you're looking. Don't take recruiter/interview calls during work hours. Don't use company computers to scrub job boards and handle applications.
Your impulse is to walk away, and that's a hard impulse to fight, but believe me it will look better during interviews when you don't have a gap on your resume.
How will you answer questions about that? "Oh, I walked away in a huff when I didn't get a raise" signals that you could be a potential problem if/when problems arise at your new employer as well.
Every company has financial hiccups. Even if you aced your work every single quarter there are going to be cashflow problems somewhere else. Dig in, put your ear to the ground, and find out what is really happening in your company.
