Vacation days are designated days off from work that employees can use for rest, travel, or personal activities. These days are typically part of an employee's benefits package and can vary based on company policy, length of service, and local labor laws. Employees may need to request these days in advance and may be required to use them within a certain timeframe. Employers often encourage the use of vacation days to promote employee well-being and prevent burnout. Unused vacation days may sometimes roll over to the next year or be paid out upon termination, depending on the company's policy and local regulations.
