Looking at the workforce, 56 percent of full-time employees are happy with their job, but if there's free food involved, that number jumps to 67 percent, USA Today reported.

Only 16 percent of those polled get free snacks at work, the survey found.

It may not be surprising that millennials consider work food more important when compared to other age groups. They also said they wish employers would offer more snacks.

Free goodies are apparently so important that 48 percent of those polled said they'd change jobs if they were offered more perks, USA Today reported.
