Everyone could use more money, but how can you tell when you're really underpaid?
The answer isn't to poll your coworkers or friends and compare your salary against theirs. For starters, you can't be sure that everyone you talk to will be 100 percent truthful.
Also, it's impossible to know whether you're comparing apples to apples — they might have certifications you don't know about, or job experience that bumps them into the next pay bracket.
But of course, you also don't want to just sit around hoping for the best, while your salary stagnates. To find out if you're really underpaid, watch out for these signs that you're overdue for a raise.
