Your employees know they could do better. Or at least they think they can, and they're definitely ready to complain about it. They want more money, better titles and less work—and more free snacks. One in five employees—about equally split between men and women—said they expect to change jobs in the next year, but men and women had different demands.

According to a new survey out from Staples Advantage (yes, that Staples), it was actually women who were looking to move for hard-charging, type-A reasons. They were more likely to leave to get a higher salary and to find more challenging work, when compared to men.

"Every woman I know, particularly the senior ones, has been called too aggressive at work," Facebook Chief Operating Officer Sheryl Sandberg told The Guardian last year. Sandberg's bestseller, "Lean In," became a beacon for female leadership in the corporate world. On the flip side, men were more likely to leave to find a stable business—and a flexible work schedule. We're all overworked, that's not a surprise: About half of all employees work more than eight hours a day. Men report working more than a full day slightly more often than women, 51 to 47 percent.

Still, the survey shows that women are more "type-A" about it, and they are more likely to complain about the extra hours and feeling burned out. Men, however, were more likely just eat it and shut up, continuing to work after they got home on weeknight and weekends.

The data comes from a new survey by Staples Advantage, the business-to-business division of the office supply company. Of course, studies have found that everyone tends to overstate how much they work, and men especially are prone to faking excessively long work weeks. The types of jobs that men and women hold could also explain part of the difference. It's no surprise that employees are jumping ship. They can't even get a break! About half say they don't feel like they can get up for a break, and the same number eat lunch at their desks. A full 23 percent of employees say that they "usually" or "always" continue working at home after the standard work day is done, and 39 percent work on the weekend at least once a month.
