A similar job listing on your company website offers much higher pay.
"If there are multiple positions like yours at the company, the job description closely resembles yours, and the salary is higher, that's one of the most obvious signs," says Taylor.
Stay on top of this by searching your own company's job postings every now and then to monitor what new employees are being paid, "and to see if that feels reasonable given your current level of experience and role in the company," adds Michael Kerr, an international business speaker and author of "The Humor Advantage."
Your firm's revenue has taken off, but your salary has barely budged.
If your company is private, it's certainly harder to measure revenue growth versus a public company. "But you're likely having discussions about corporate growth with managers in your normal course of business," Taylor says. "This is an opportunity to dig deeper. If you're armed with the fact that the firm has seen 20% growth in one year, but your salary is under par, you'll strengthen your argument for a raise."
Research tells you you're underpaid.
This is a pretty solid sign.
"You must stay on top of the current salaries for your type of position," Taylor says. "There are many online sources for this, including PayScale.com, Glassdoor.com, Indeed.com and Salary.com."
Kerr says using an online salary calculator to see where average wages are, or should be, for someone in your role, with your level of education and years of experience, can be a good starting point and may indicate if there's a huge discrepancy between your wage and the going rate.
The salary for your very first job was far below market — and it hasn't changed much since.
Think back to the salary you accepted for your first job (maybe you accepted a salary you knew was low because you were desperate for a job). Now think about your progression from there. If your income hasn't changed much, you're probably underpaid. "It can be difficult to play catch up if you started low," Taylor says.
You make less than your colleagues with similar levels of experience and education.
Although people rarely talk openly about money — and in many companies are prohibited from doing so — there may be association or industry networking events where people who work in similar fields with similar levels of experience share anecdotes about their workplace and the topic of salary comes up, says Kerr. "If the discussion makes your jaw drop, then there's a good chance you are being underpaid."
Your level of responsibility has increased, but your salary hasn't.
"If your boss keeps piling on added duties, extra work, and especially more responsibilities without any increase in compensation or even a discussion about it, this may be a sign that you are underpaid," says Kerr.
Another sign: Your title has been upgraded, but it's not reflected in your paycheck, says Taylor.
You're in a specialty area that's not in high demand.
Some jobs are in higher demand than others. "Cyber security and SEO/SEM marketing are hot job specialties, for example, whereas certain other positions are becoming more automated, or there may be great supply, but reduced demand," Taylor explains. "Factor in where your field of expertise stands in the general job marketplace."
Your mindset is 'I'm just happy to be employed.'
Have you fallen into a complacent mindset of being happy just to have a job? Most managers can sense this and will not go out of their way to make you an "absurdly happy" employee, if you're already a happy employee, she says.
You haven't had a performance review or raise in over a year.
If it seems that the time for your performance review has come and gone — or it came without a raise — you might have reason to believe you're underpaid, says Taylor.
You have a gut feeling.
"If you feel inclined to take extra long lunch breaks, steal the occasional office supply, or in some other small way take advantage of something in your workplace because you feel you are 'owed' it, even at a subconscious level, this could be an obvious sign it's because at some level you feel underpaid," says Kerr.
Your salary increases are negligible.
Perhaps you did get a raise last year or for the last two years, but they're in the 1% to 3% range consistently. Depending on your department, company, and industry, particularly if you're on the lower end of the scale, you may be underpaid, says Taylor. "A lot depends on the other feedback and information you're getting along the way."
Your boss is evasive when you want to discuss your career path.
Do you find that it's virtually impossible to discuss your long-term career growth with your boss? He or she may be reluctant because that may lead to a salary discussion or something complex that they're unprepared to discuss. "That's not something you should be willing to sweep under the rug for very long, even if your boss is," Taylor advises.
