A new study by LinkedIn surveyed more than 13,000 Millennial job seekers to find out what it takes to get them to work for you, and offers some insights into the lengths some employers are going to need to go to hire the best talent from this generation.

Perhaps the fact their underemployment rate is still hanging at 26 percent plus (and comes with lower salary earnings, too) is making Millennials rethink what matters in a job.

Here are just a few statistics the survey revealed:

93 percent of Millennials are eager to learn about new job opportunities. That means just 7 percent of them are fully satisfied in their current role.

30 percent of working Millennials say they plan to leave their current job within a year.

Translation: Your smiling Millennial work force isn't as happy as you think.

The No. 1 reason for not accepting a job is not knowing enough about what it's like to work for the company.

Of all the generations working today (Millennials, Gen X, Baby Boomers), Millennials are the most likely to follow you on social media as a way to learn more about you as an employer.

Translation: Your failure to reveal your employment brand via social media is hurting your recruiting efforts.

64 percent want to know about perks and benefits.

The No. 1 thing they want to know about your company is its core values and beliefs.

Only 30 percent of Millennials are focused on purpose-driven work, whereas almost half of all working Boomers (48 percent) want to do work that feels meaningful.

The top two reasons Millennials leave for a new job are: A) more money and benefits, and B) more career opportunities.

Translation: You might be marketing the wrong aspects of your employment brand to Millennials. Or, even worse, you may not have what they are looking for.

Think twice before saying, "I'll skip it," with respect to hiring Millennials

Millennials make up half the current working population and will continue to dominate over the next decade. Even though Baby Boomers have delayed retirement, they're still exiting the work force at a rapid rate. And with just 46 million Gen X behind them, as compared with more than 70 million Millennials, the talent gap will require hiring from the youngest generation in the work force.

In short, if you aren't building a marketing plan to recruit, train, and retain the best and brightest Millennials, your company could suffer in the future.
