1 In 5 Employees Will Quit Their Job In 2016

Next time you're hanging out by the watercooler with your five coworkers, know this - at least one of them won't be working with you in 2017.

That's because one in five workers will find another job in 2016, a new report says.

The report, done by CareerBuilder, found that 21 percent of workers plan to leave their current job in this next year, which is up 16 percent from 2015. This number only increases among millennials, as 30 percent of people aged 18 to 34 years old plan to have a new job by 2016.

In general, 34 percent of people are constantly searching for a new job, even though they're happy with their employer and the work they do, the report found.

"Just because a person is satisfied with their job doesn't necessarily mean they aren't looking for new work," Rosemary Haefner, chief human resources officer at CareerBuilder, said in a press release. "Because of this, it's critical to keep up with your employees' needs and continue to challenge them with work they feel is meaningful."

Survey respondents said they consider job stability, affordable benefits, location, a good boss and a good work culture as factors more important than salary when considering a new job, the report said. Many coworkers also want to see half-day Fridays, a fitness center at their workplaces and be offered catered lunches to make their job experience a little better.

But quitting a job isn't easy, especially when finances are tight. As Tess Vigeland wrote for Quartz, most people don't quit their jobs until they have another lined up.

"We say goodbye to one cubicle on Friday and say hello to a new one on Monday," she wrote. "We believe that quitting without a backup plan would be impossible and selfish and unwise, dooming our careers, our finances, our families, and quite possibly bringing about the apocalypse."

And while this isn't always the case, Vigeland suggests those interested in quitting their job without a backup plan make sure they are financially stable. Workers should consider how much of an income loss they're willing to suffer and for how long.

"Do your homework by talking about this with the people who will be directly affected by this decision-your spouse, for example, as well as family members whom you currently support or who you might turn to for a loan in a rough patch," Vigeland wrote. "Money discussions are never fun, but in this case, they've got to happen."

And for those quitting without a backup plan, it's still beneficial to "do something" in the meantime, Vigeland noted. Spending too much time "sitting on the couch eating bonbons and getting depressed" will only negatively impact your motivation and career goals, she wrote.

Vigeland also suggests people who recently quit their job network with people they know and figure out what they want from work.

If you are one of the 1 in 5 Americans planning to quit your job, it's important to know which job markets have a spot for you. Luckily, WalletHub just published its list of best cities for jobs in 2016, based on which cities offer the best job opportunities and employment growth.

"Your luck of finding employment, of course, depends on where you live," WalletHub reported.

Plano, Texas - where Toyota just moved more than 3,000 jobs - tops the list, with Overland Park, Kansas; Austin and Irving, Texas; and Salt Lake City rounding out the top five.
