Deferred vacation days are often subject to certain restrictions, such as a maximum number of days that can be carried over from one year to another. Some employers may also require employees to take a certain number of vacation days each year, regardless of whether they have any deferred days.
If you have deferred vacation days, it is important to remember to use them before they expire. Some employers may have a policy that forfeited deferred days after a certain period of time, such as one year. If you are unsure about the rules for deferred vacation days at your company, you should check with your human resources department.
