1. Flexible time will be bigger than ever. This may not be a benefit in the coming year as much as an employer strategy. More than ever, employees are clamoring for flexible work hours — and it's about time employers listen up.

Survey findings by tech staffing firm Modis underlined the importance of flexible work hours: More than half of employees said they are among the most important workplace perks.

"People are happier when they are able to take care of things when they come up," Jack Cullen, president of Modis, told CNBC. "I think employers are recognizing this is real, and (flexible hours) is a way to really attract and keep people."

2. More negotiation in benefits will become the norm. According to Robert Half, 43% of CFOs said they are willing to negotiate perks and benefits with new employees. And 40% said they are more open to negotiating than in the past, compared to only 6% who were less open than previously.

Expect it to be more common for new employees to negotiate perks such as more PTO days in the coming year.

3. Parental leave will remain in the public eye. Tech giants including Netflix, Adobe and Facebook garnered a lot of attention and praise in 2015 when they expanded their parental leave policies. Sure, not every company will follow suit, but where Silicon Valley leads, others will follow.

Presidential candidates are weighing in on parental leave as well, ensuring that it becomes an election issue.

4. Unconventional wellness. There was a significant jump in wellness offerings from 2014 to 2015, and they will only jump more in the coming year.

While employers are continuing standard wellness practices such as smoking cessation programs and premium discounts for getting an annual risk assessment, put your money on a rise in out-of-the-box wellness offerings too — including company-provided fitness trackers; corporate challenges, yoga and other fitness classes at the office and maybe even (yikes) "Biggest Loser"-type competitions.
