American workers had 206 million unused vacation days last year — that's $66.4 billion worth of benefits left on the table.
Many professionals may think the less time they take away from the office the more likely they are to impress their boss. A study from Project: Time Off found the opposite: It said employees who use their vacation days are actually more likely to get a promotion or raise, versus employees who end the year with unused time off.
German automaker Daimler has implemented a "Mail on Holiday" email policy that ensures its employees are taking full advantage of their time off, without fearing an overflowing inbox when they return. Through this policy, employees have the option to set their emails to autodelete while away from the office.
