Salaries are no longer secret, at least not to most millennials.
The Cashlorette, a Bankrate company, found in a survey of more than 1,000 U.S. adults that 63 percent of 18- to 36-year-olds say they have shared salary data with an immediate family member, 48 percent have shared with friends and 30 percent have shared with co-workers.
That's in comparison to 41 percent of baby boomers who've shared that info with family, 21 percent who've shared with a friend and 8 percent who have shared with a co-worker, the survey says.
So, what happens if you tell a co-worker your salary?
According to Traci Fenton, chief executive officer of leadership firm WorldBlu, it could do some good. Offices have the potential to function better if compensation is shared among bosses and co-workers.
"Everyone gossips about how much people make and everyone's wondering — it's very toxic and wasteful," she says in an interview with career-advice website Monster. "When you're open and transparent, it cuts down on the noise, and allows people to be more efficient."
Sharing salary data can also let you or someone else know if they're not making enough. According to the survey, it could "help you determine if you're actually getting paid fairly, or give you the boost to work up the nerve to ask for a raise."
