A long-standing, unofficial workplace “rule” is that you don’t talk about your salary with your co-workers. But Millennials aren’t big on following the rules …and it’s paying off. A study by TheCashlorett.com. found that when it comes to 18- to 36-year-old U.S. workers, 30% have told their co-workers what they are making. 33% of older Millennials, ages 27 to 36, say they’ve shared their salary with their co-workers – that’s more than any other age group and four times more than Baby Boomers (53 to 71) at 8%. Why is sharing your salary paying off? Because knowledge is power. "Knowing what your friends and colleagues make in a similar field is empowering in making sure you're being compensated fairly and gauging when it might be time to move on or request a raise," said Sarah Berger, founder of TheCashlorette.com.
